Abstract
Beginning in 1948, archaeological surveys and excavations in northwest Iran brought to light evidence of cultural developments related to the movements of people who colonized vast parts of the Near East from northeast Anatolia to southern Levant in the late 4th and early 3rd millennium B.C., prompted by environmental changes, population boom or shortage of biological resources in their homeland. The period is best known in the archaeological literature as the Early Trans-Caucasian (ETC) or Kura-Araxes culture, and is distinguished, by a disparate black burnished pottery with incised decorations. Here is published for the time a sample of decorative patterns on the related pottery from Yanik Tepe. The main question of the study was: To what extent did the newcomer potters communicated on this pottery the artistic traditions they had brought with themselves from their homeland? Data gathered through museum and library enquiries were used to carry out a comparative study. Data analysis was of qualitative nature, and the study represented one of culture-historical.

Introduction
The question central to this study is: Does the Kura-Araxian pottery tradition at Yanik Tepe reflect traits induced by indigenous experimentations, or it was simply developed via foreign inspirations and cultural interactions? 
As stated, the pottery assemblages from Yanik Tepe had remained intact since their initial movement to National Museum of Iran after the close of excavation. Preparatory work was therefore required before deciding on or attempting any sort of study. Accordingly, the whole collection was recorded and washed before the decorated sherds were singled out and sorted into such groups as geometric motifs, animal motifs, plain, and miscellaneous. This was followed by the documentation process that involved photographing, drawing and registering the entire formal and technical attributes of individual pieces. Attempts were made to exclude from the final sample the patterns that were identical to those already published by Burney in various places. Also to meet the diversity criterion, pieces were selected from as varied excavated exposures as Areas or Trenches H, HX, K, L, M, P and different Levels, viz. YT.HX3, YT161HX, YTHX4, YT.HX1, YTK3, YT.HH1, YTH5, YT.HH1A, YT.C5, YT.P2, YT.LIA, YT.HH10, YT.HX1, YT.L3PRMII, YT.P2, YT.39C, and YT.RH13.

Yanik Tepe
A key site in the archaeology of the eastern Urmia Lake Basin, Yanik Tepe is 30 km southwest of Tabriz and 6 km from Khosrowshahr, within the village of Tazeh Kand on the Talkheh Rud. Burney excavated the site in 1960, 1961 and 1962, shortly after its identification in 1958-9. Yanik Tepe consists of a high mound and a low mound, rising 16.5 m and 1.50 m from the surrounding lands, respectively. With an original total area of about 6 hectares, it represents a type-site of the Kura-Araxes culture in Azerbaijan (Burney 1963, 138). Large parts of the site are now destroyed. Typical of the culture that flourished at Yanik Tepe were round and rectilinear houses and a distinct pottery tradition. Most intriguing are those types that resemble the material from the vast cultural horizon of eastern Anatolia and the early Trans-Caucasia of the mid-3rd millennium BC. 
Building on the results of his excavations at Yanik Tepe, Burney divided the whole Kura-Araxes (or the ETC) sequence to the three discrete periods of ETC I, ETC II, and ETC III, where the earliest period marks the birth of the culture in its motherland, the second is associated with round structures and decorated pottery, and the latest sees the predominance of rectilinear architecture and virtual disappearance of decorations on pottery (Summers 2004, 619-620). For a more recent and detailed discussions on the chronology and dates as well as the stratigraphy of Yanik Tepe, the reader is referred to Summers 2013; 2014, 157-159. 
An idiosyncrasy of the Early Bronze Age at Yanik Tepe is the handmade, black or gray burnished pottery with incised patterns. The technique is reminiscent of woodcarving and was presumably inspired by the densely forested landscape of the homeland of bearers of the culture who came to the rather sparsely wooded regions of northwest and west Iran. The technique was widely applied to pottery along with excised patterns, filled with white and occasionally ocher pastes. 
Designs like birds and highly stylized rams or ibexes with curled horns, and bands of geometric motifs were carved on bowls, jars and footed pedestal vessels and small cups, the pottery forms common to the period. 
The Middle Bronze period marks a shift in architectural styles as the related houses were built in a rectilinear plan using mud bricks. The thick walls spoke of two-storied buildings. The use of decorations diminishes, and the so-called graphite burnished technique emerges on a few examples of cups. Vessels are relatively finer, and burnishing is more frequent. Pottery forms show no considerable differences between the two periods (Burney 1962). However, the so-called Nakhichevan lugs, common to the latter period, occur now only in a vestigial form. 

Kura-Araxes Pottery of Yanik Tepe
This section gives a description of the pottery with a special focus on decorations, along with a series of so far unpublished illustrations, which besides enriching the existing literature on the pottery history, are intended to improve the current picture of the evolution of pottery styles through the long Kura-Araxian horizon at Yanik Tepe. It is notable that, as stated earlier, the pieces and decorations published here have not been introduced in any earlier publications and have been selected from various trenches and levels to ensure a representative sample to the possible extent. 
The Kura-Araxian pottery, coming in disparate wares and decorations, represent a new style that newcomer artisans had brought with themselves to northwest Iran. It is characterized by dark gray or shiny black or light brown color; vessels are handmade, contain mineral tempers, and show a burnished surface bearing an assortment of motifs such as spirals, “ram horns” and concentric circles or “eyes” (Burney and Lang 1971). In the Kura-Araxes Period I, rail rims were common, the Nakhichevan lugs were not yet emerged, and some Chalcolithic forms and decorative techniques persisted (Glumac and Anthony 1992). Related material occurs at most sites in Caucasia, the eastern fringes of Anatolia, and Geoy Tepe K1 (Sagona 2000).
The Period II is distinguished by the abundance of elbow handles and advent of semi-circular Nakhichevan lugs; the rail rims are utterly absent (Seyedov 2000). Notable in the assemblages is the ubiquitous concentric circles or “eyes” and incised triangles or chevrons. The pottery with its distinctive incised decorations shows influences from neighboring spheres. Various motifs are discernible. Animals, birds and fish occur in abundance. Birds appear as stylized representations on jars and bowls with decorations always reserved for the base or close to it. Also present are very simple geometric designs, bands raging from plain examples of undulating lines to those of a very intricate combination of nested designs, horizontal grooves or hatches, zigzags and doted patterns, rows of geometric motifs like lozenges with adjoining triangles filled with a various combinations of incised dots in diverse arrangements, swastikas, small lozenges and slanting motifs. Spirals and concentric circles were applied in incised form and evolved into an excised form with the related patterns filled with a white paste or lime. A frequent motif is the sharply angled triangles evoking the mountain motif as is the incised patterns imitating cuneiform signs. They are much finer compared with the ordinary handmade pieces. The Kura-Arax II material from Yanik Tepe find parallels in Geoy K1, Yakhvali, Ravaz (Kohna Shahar), Baruj, Haftavan VII and Godin IV (Burney 1961, 1962; Kleiss and Kroll 1979; Asurov 2000).
Typical to the Kura-Araxes III assemblages are the incised spirals and loop handles attached to the rim. The concentric circles occur in a higher frequency (Burney and Lang 1971, 67; Seyedov 2000, 19). Nakhichevan lugs show a gradual decline. Related pottery is known from Geoy K3, Godin IV, Shengavit IV, Kul Tepe of Nakhichevan, Kvatskhelebi in Georgia and sites in the Koban area of East Anatolia (Burney 1961, 1962; Burney and Lang 1971; Sagona 2000).

Introduction
The art of sealing and making stamps has a very long history in the olden times of mankind.  Since the appearance of stamp seals in northern Mesopotamia during the 6th millennium B.C, they have been used throughout the ancient Near East until the innovation of the cylinder seal in the second half of the 4th millennium B.C. Cylinder seals were the preferred administrative tool in Mesopotamia during the 3rd and 2nd millennia B.C.  The seals of Persia correspond in their types and use to those of Meso-potamia, beginning with amuletic pendants, and developing into stamp to cylinder seals.
Like cylinder seals, stamp seals could be made from stones; metal and clay. The images carved into the seal face itself ranged from simple geometric patterns to elaborate scenes of human and divine images. Seals are important to the study of ancient art and can, help to define chronological phases. they serve as a visual chronicle of style and iconography.
The images on it, contain enormous information which can be used to clarify the customs, ethnic be-liefs and to some extent the social, religious, political, economic, art and architectural conditions.  Fur-thermore, this information can be employed to culturally reconstruct the ecosystem of the forgotten ancient societies.  On the other hand, the stamps seal was used as a document to facilitate the transfer of commercial goods to neighboring or distant cultural areas.  It also provides information about neigh-boring and other cultural areas and shows the links between ancient societies and their relationship in joint organizations (Collon, 1990: 11).
This article reports the result of a preliminary research on a number of exchange stamps and cylinder seals which were identified and registered during the re-organization of the objects of the National Mu-seum of Iran in 2010.  They were part of a collection of seals from the ancient sites of kaluraz. These works contain valuable and important information from various artistic, cultural, economic and com-mercial aspects in different historical periods in this cultural field.  
The purpose of this study was to stablish the method of construction; the typology and the age of these seals; the geography of this cultural field; the method of making imitation stamps and recognizing their designs.  Research Questions and Hypotheses are specifically explained below:
• Where was their main origin and from which historical and cultural context?
• Do these seals have a particular local style or their style is influenced by other cultures?
• The seals found in the kaluraz Archaeological Site belong to which historical period?

Material and Methods
To achieve this aim, we did literature review using the currently available visual documents and exam-ined eight seals of the Damage and crockery cylindrical seals of Ali Hakemi in the coin and seals section of the National Museum of Iran in 2010.  Our analyzes is based on the excavations information (ob-tained during the field work in this cultural field) and the designs and descriptions of the concepts of the symbols of these seals.  
The National Museum of Iran has a large collection of different seals from various historical periods.  For example, the flat and cylindrical shapes seals that have been obtained in archeological excavations of the last five decades from the ancient sites of northern Iran in the geographical area of SepidRood.  

Geographical Setting
Sepidrood (the name of a river) catchment is located in Gilan province, south of the Caspian Sea.  Due to the climatic conditions; suitable environment and natural resources, this geographical basin has long been considered as a suitable habitat for living and has contributed to the creation of ancient cultures in this area for thousands of years.  The native name of SepidRood, especially in Gilan province, is Es-piyeh or Espiro (Domorgan, 1338: 209) in Gilaki language means white river.  Some Avestan scholars consider Sefidrood to be the same Daiti river in Avesta (Khodzko, 1975: 19-40).  Diakonov mentions the old name of Sefidrood Amard or Amardos (Diakonov, 1379: 79, 210, 312 and 623).  
The history of archeological research in the Kaluraz Valley dates back to the 1960.  During this period, a delegation headed by Ali Hakemi with the cooperation of archaeologists such as Mahmoud Kardvani; Abdolhossein Shahidzadeh and Ali Akbar Sarfaraz excavated some part of Gilan.  They worked contin-ually in several seasons for many years.  They collected valuable artifacts including stamps from Lilijan, kaluraz, Joban, Sandos and other archeological sites of Gilan.  The Stamps of current study were dis-covered and collected by Ali Hakemi and Abdolhossein Shahidzadeh, during the archaeological study and excavations between the years 1965 to 1969. 
During 1967 to 1969, Ali Hakemi studied Kaluraz, which includes a collection of cemeteries such as Ganjpar, Kafarkesh (Daghudalan) Zarindar and Jalalieh (Hakemi, 1347: 22-22).    The findings of Ali Hakemi are maintained and protected in coin and stamps section of the national museum of Iran.   
In 2010, we explored the cemetery and the ancient hill of Kaluraz in the west of Sefidrood, which is located alongside the road from Tehran to Rasht and 85 kilometers far from the coast of the Caspian Sea in Gilan province.   

Result
Excavations in the last five decades in northern Iran, especially in the Sepidrood catchment area, have led to the discovery of unknown cultures, in the ancient sites of Marlik, kaluraz, Nasfi, Joven, Jamshid-abad and other sites in the cultural area, during the late second and first millennium BC. They were achieved from different periods of the second millennium BC until the Sassanid era.  
Preliminary study on these seals, collected from Marlik Cemetery and northwestern sites such as Ha-sanlu, was able to give us a fresh look at the environmental conditions of the region, cultural relations and trade exchanges from socio-economic institutions during the Iron Age of this cultural field. The role of animals such as mountain goats, river fish, hunting birds, native trees of the region and agricul-tural fields indicates the livelihood and livelihood economy of the inhabitants of SepeedRood basin, which reflects a part of the environment and connections of the ancient Kaluraz area.  The artistic qual-ity in drawing the creatures is one of the characteristics of the artistic style of these seals.  This type of design can be seen in other works of this cultural field such as Marlik Cemetery.  The only seal whose style of engraving is different from other seals is a seal with a row of male mountain goats moving backwards.  This type of role is influenced by the stamping style of the Assyrian period, which can be entered into Kaluraz as a result of commercial exchanges. Although the lack of inscriptions on these stamps makes dating difficult, valuable cultural findings such as gold cups; ornaments, and beads made of imitation and bronze, show the characteristics of the Iron Age in Iran and cultural ties in this period.  Gold and silver goblets and ornaments and flat bronze seals and types of pottery obtained during the excavations of Kaluraz Cemetery, indicate very dynamic economic conditions with close relations and economic exchanges of residents with neighboring areas in the south of the Caspian Sea and between different geographical areas in Lake Urmia, such as Hasanlu.  In these areas the effects of the common style of local art and the influence of the Mitani style on cultural findings can be seen.

Conclusion
Archaeological excavations in the cemeteries and the geographical basin of SepidRood in the last five decades has provided valuable archaeological knowledge of this cultural area during the late second to the first millennium BC, including specimens of wrought iron and bronze beads from the whole tomb.  The results of this research led to documentation of the findings and comparison the finding with other important settlements of the first millennium BC, in contemporary cultural horizons such as Marlik, Toul Talesh, Hasanlu and Mesopotamia.  Furthermore, a general conclusion about the process of typol-ogy and stylistics of seals is presented.

Abstract
Prior to L. Afshari’s fieldwork in Ramhormoz, the known Achaemenid sites from the plain only amounted to 17 in number. Yet, given factors such as favorable climate and fertile soil for agriculture, existence of important rivers such as Kupal and Sandali, proximity to such trade routes as the Susa-Persepolis royal road as well as to the two major Achaemenid capitals of Susa and Persepolis, we deemed the figure to be rather underrated, believing that there must be much more concomitant settlements in this plain. During our investigation, the sites recorded by the previous team were re-visited and new coeval sites were also identified. The survey of 2020, directed by one of the authors (L. Afshari), did not encompass the entire Ramhormoz plain. Covering only its middle part straddling the Ala River with a total area of about 53000 hectares (530 sq. k), the survey recorded 36 Achaemenid settlements. Identification of the relevant sites was based on Khuzestan’s local pottery of the Achaemenid period reported from Tape Daroughe. In this study, the impact of geographical factors such as the presence of large rivers and fertile lands on the genesis and prosperity of settlements was evaluated. The surface architectural finds are suggestive of interactions between rural and nomadic communities. Results of the surveys indicated the proximity to ancient royal roads and access to water sources and pastures to be the determining factors in the distribution pattern of Achaemenid settlements over the Ramhormoz plain. This survey program aimed to identify and locate the Achaemenid sites in the Ramhormoz plain, to examine their interrelations, to record their characteristics through sampling and observing pottery pieces, to establish a relative chronology for them based on the typology of surface pottery collections, and final to draw cross-regional typological comparisons with major sites in other parts of Iran, South Mesopotamia, and East Anatolia.

Introduction
The vast region of Ramhormoz stretches up to the mountain belt of Khuzestan to the north. Sitting in the eastern Khuzestan plain at an elevation above sea level of 120 m, the plain of Ramhormoz encompasses a total area of 620 sq. km. All across southwestern Iran, Ramhormoz is the region with the least archaeological investigation. Despite this paucity of work, recent studies have demonstrated the regional settlements (in both mountains and plains) to be integral to any understanding of the culture of the Achaemenid period. Geographic location of the region, the nature of settlements in the transition zone between plains and mountains, and their continuity and cultural ties with each other also furnish a pattern for grasping the Achaemenid world’s settlement policy. In addition, given its strategic location during the concerned period, the plain assumed a central role in the interactions between Iran, Mesopotamia and Anatolia. It is of great importance also because of its location on the Royal Road from Susa to Persepolis.
The southwestern region of Iran played an important role in establishing cultural, economic, and political interactions with surrounding areas such as Mesopotamia and Anatolia throughout the 1st millennium BC. The number of archaeological studies conducted in the Ramhormoz area has been quite limited. Despite the lack of archaeological information, the studies carried out in recent years have shown the significant role the cultures in the region (both the mountain and plain settlers) played in understanding the Achaemenid Culture.
The significance of the region was further revealed with the surface surveys carried out by Donald Mc Cown in the region and the excavations he conducted at Tol-e Geser (McCown, 1949, 1954). Surveys conducted by Wright and Carter in 1969 also pointed to connections between the region’s lowland and mountainous parts of southwestern Iran (Wright and Carter, 2003). Although the dimensions are different, it has been observed that the settlements share some common features with the mountainous parts of Persian geography. As a result of contemporary archaeological resources and the survey conducted under my supervision, the characteristics of the Achaemenid settlements in the Ramhormoz plain in Southwest Iran were reanalyzed. The influence of geographical factors such as the presence of large rivers and fertile lands on the formation and prosperity of the settlements and the relations between sedentary, rural, and nomadic communities were studied. Also, the transformations in the settlement system, distribution, and population differences during the Achaemenid period were revealed and subsequently / mapped.

Discussion
This survey program aimed to identify and locate the Achaemenid sites in the Ramhormoz plain, to examine their interrelations, to record their characteristics through sampling and observing pottery pieces, to establish a relative chronology for them based on the typology of surface pottery collections, and final to draw cross-regional typological comparisons with major sites in other parts of Iran, South Mesopotamia, and East Anatolia. The realization of the latter aim will have important implications for the Achaemenid archeology of southwestern Iran, altering the existing views. In light of our findings, it is possible to propose a distribution pattern for the settlements in the middle of the Ramhormoz plain as being clustered in two regions, viz. northwest and southeast, on both banks of the Ala River. The finds of primary importance from the settlements of the plain are pottery assemblages. To explore the Achaemenid pottery, they were first classified by shape, which consisted of the five groups of carinated bowls, bowls with a spherical body and a simple rim, necked jars, short-necked jars, and storage jars. This was followed by comparative studies for dating the pottery. Our observations show that the Achaemenid pottery traditions continued well into the subsequent period after the demise of the empire.
Thus, it is notable here that the materials and settlements discussed in this paper can potentially extend in date to as late as a century after the Achaemenid period. In terms of technical characteristics, the pottery splits into five groups: common, light green-slipped, red-slipped, eggshell, and painted wares.
Drawing on historical sources and archeological findings as well as the conducted studies, the villages across the plain tend to be clustered around or be related to the Susa-Persepolis trade route. The rich geography of the plain has informed the dynamics of its settlements over time. Notwithstanding the severe disturbances induced by modern settlements and agricultural and industrial activities, the identified settlement centers reveal direct or indirect link with the commercial or military routes of the Achaemenid times. In other words, their formation along the commercial routes was primarily meant to facilitate intra- and cross-regional contacts. The proximity of settlements to the royal road between Susa and Persepolis evinces the integral role the road played in the cultural interactions of the Achaemenid period. Therefore, archaeological studies directed by Esmail Yaghmai are important in detecting the remains of settlements along the royal road linking Susa to Persepolis as they reveal the characteristics of the settlement policy. 

Conclusion
With the completion of the archaeological investigation in the Ramhormoz plain and the study of the findings and data obtained from this investigation, it seems that a general understanding of the cultural remains related to the Achaemenid period and the distribution of the sites of this period can be achieved to some extent. It was thus revealed that proximity to commercial roads and access to water resources and pasture were the main determinants in the distribution model of Achaemenid settlements. Rich pastures for nomads, the potential for irrigated agriculture for settlers, and access to communication routes provided advantages for both lifestyles. Therefore, the settlement pattern is more associated with roads. When the location of the settlements and their distance to each other are examined, it is seen that the frequency of settlements on the Susa-Persepolis Royal Road is very high. Settlements are located on the road within short distances of each other, which shows that the road is a determining factor on settlements in the region due to its socio-economic advantages.
Ramhormoz plain shows that the Achaemenid settlements in this plain maintained strong intra- and cross-regional cultural and economic ties. In terms of extent, Tol-e Ishan Seyyed Shabib or Tol-e Toupi, Tape Mava, Tape Mehr Alnesa and Tape Kheyr Alnesa appear to be examples of such type of villages. With respect to the location of settlements and their distance from each other, a concentration of settlements is discernible along the Royal Rod—they are clustered along this road at close intervals. This fact indicates that routs played a decisives role in the formation of regional settlements, and that the Royal Road yielded multiple economic and political advantages. In general, it is possible to say that most of the settlements in the Ramhormoz plain lie on the riparian areas or along the Royal Road from Susa to Persepolis, and judging by the pottery collections, there clearly were close interrelations between these settlements and interactions with neighboring regions. On this very basis, one may safely surmise that a local and highly advanced pottery industry prevailed in the plain during the Achaemenid period. Cross-comparisons of the surface pottery assemblages from the Ramhormoz plain with the excavated material from sites in southwestern Iran, southern Mesopotamia and eastern Anatolia indicate the presence of early, mid- and late Achaemenid ceramics, suggesting that the Achaemenid cultural horizon continued uninterruptedly over the plain between 330‒550 BC.

Abstract
An archaeological survey was carried out in 2019 with the aim of identifying and investigating the Ilkhanate period on the banks of the Aras River in East Azerbaijan province. The present study focused on the study of the large, wide, mountainous and impassable gates called “Sham Valley”, which was formed by the confluence of two major rivers of the Aras with Aqchay, which extends near the city of Khoy and was important in the field of trade relations and culture. The strategic and geopolitical position of the region with the surrounding regions such as the Caucasus, Turkey and Central Asia, as well as its geoeconomic position as a corridor of communication corridors led to many cultures and civilizations from the second millennium BC to later epochs. Alternating in this area. In other words, the main factor for the emergence of these ancient settlements is the location of the trade routes, the easy inter-regional and supra-regional communication, especially during the Mongolian Ilkhanate period, which played an important role in the development of cultures in the Sham valley. On the other hand, due to the religious importance of this region during the Mongolian Ilkhanate period, based on its foreign policy and the existence of important churches such as the church of Saint Stepanos Monastery, the Qarah Church and Zur Zur Church, which are known in the world and in whose case there are no reports or documents, there is no archaeological activity; therefore, a careful study of this area, as well as the study of the ceramics obtained from these areas, has provided useful information about pottery technology and the social structure of the area in different cultural periods, especially the Ilkhanate period.

Introduction
As a result of the study, 53 ancient sites from prehistory to Islamic times have been identified and recorded; areas such as the Naneh Maryam Cemetery and the Chupan Church are the most important. In these areas a significant number of Middle Islamic centuries ceramic pieces were carved in simple glazed form. It is important to identify the constituents of each pottery, to determine the difference in composition and constituents between the samples, to determine the percentage of each constituent, to determine the baking temperature of the pottery based on the available minerals, and finally to archaeologically study its origin and understand the social structure of the area. Knowledge of the pottery’s components can provide us with useful information about the geographical origin of pottery in the region and its consumers.

Materials and Methods
Thin-section petrography is one of the common and widely used methods in geology and archaeology. This method is employed to examine a broad range of materials such as rocks, minerals, ceramics, slag, bricks, and plaster (a mixture of lime and gypsum). In this technique, an extremely thin section of the rock or ceramic object under study is prepared. This section is thin enough to allow light to pass through it. Then, by placing it under a polarizing microscope, the minerals present can be analyzed. Since minerals exhibit different properties and colors under polarized light, petrography specialists can distinguish them from one another; thus, it is possible to identify the types of minerals, their characteristics, shapes, and sizes in rock or ceramic samples (Ellis, 2000). Moreover, ceramic petrography provides valuable information regarding the technical characteristics of ceramics, such as whether the vessels are wheel-thrown or handmade, and the additives incorporated into the ceramic paste (temper). These tempering materials typically include fragments of igneous rocks, siliceous particles, and silt and clay components. All plant-based and organic materials in ceramics are eliminated at temperatures of approximately 200 to 250 degrees Celsius, leaving only their voids behind (Mousavi-Faghih, 2018).
For the microscopic studies of ceramics obtained from the Sham valley survey, a James Swift model polarizing binocular microscope was used. The magnification applied in this study was 4X. To facilitate the presentation and analysis of results, the petrographic data were organized in a table. The first row of the table lists the components constituting the ceramics, and the first column provides the name and number of each ceramic sample separately. The presence of each component or mineral in the sample is indicated by an asterisk (*), while its absence is marked by a dash (–). If the abundance is minor or trace, it is denoted by (tr). The selected samples for this study come from two sites: the Naneh Maryam cemetery area (code C.042) and the Chopan Church area (code C.053). Ceramics consist of two main parts: the paste (matrix) and the tempering materials. In ceramic petrography studies, a significant focus is given to the additives mixed into the paste. Archaeologists typically consider components larger than 0.1 millimeters as temper or inclusions. In the study of ceramic samples from the Darreh Sham sites, the petrographic method was employed to identify the components and compositions present in the ceramic paste.

Conclusion
Since the Sham Valley in northwestern Iran has been considered on the basis of texts and travelogues since the early Ilkhanate period, there is a need to inform the patriarchs about the use of pottery from the Middle Islamic period and its production. Accordingly, petrographic studies were carried out on 12 pieces of pottery from the two sites of the Neneh Maryam cemetery and the Chupan church to determine the place of production of these ceramics. On the basis of the available samples and on the basis of the analyses carried out, it was found that the composition of all the pottery studied was related to the Jolfa area and the river sediments and alluvial deposits of the Aras river, as well as seasonal and local rivers. With regard to the baking temperature of the pottery, with the exception of the site of the Shepherd Church, where all the potteries studied had no calcite and tolerated temperatures above 800 degrees Celsius, potteries from other areas tolerated temperatures below or close to 800 degrees Celsius. Two categories of inclusion or temper are observed in the composition of the paste. One technique was used in the production of all glazed ceramics. In this way, a layer of glaze can be seen on the outer surface of the sample and, depending on the desired color, a layer of metal oxide can be found underneath. Underneath the glaze layer is a porcelain layer (a mixture of fine-grained quartz and white clay), which lies directly on the clay body. Furthermore, based on the composition and petro fabric of the examined ceramic samples from this area, it can be concluded that the ceramics are almost identical and similar in composition and origin.
