Abstract
Qal’eh Ganj is situated on the south of Kerman province, on the border of Sistan & Baluchistan and Hormozgan provinces. The first season of archaeological survey of this area has been carried out in 2016. This survey resulted in discovery of 66 archaeological localities dating from Palaeolithic to Islamic periods. In the present article, we try to determine cultural connection of study area with surrounding regions and it is the reason that we can present a relative dating for the prehistoric sites (Chalcolithic and Bronze Age sites). Based on the comparative dating, chalcolithic sites encompass two periods of fifth and fourth millennium BC that introduce cultural periods of southeastern Iran, respectively, Yahya VA, Mahtoutabad I and Aliabad. The Study of surface data from Bronze Age sites indicate a cultural connection between southern Jazmurian to areas of Halilrud Basin (Konar Sandal south), Soghun valley (Tepe Yahya) and Eastern Jazmurian (Bampur Tepe) and include a time range from late fourth millennium to early second millennium BC. There were found various stone structures in Bronze Age sites which suggests different functions including graves, residential spaces and water management systems. Based on dispersal of the Bronze Age sites and their strategic location as a connection between Bampur area and Persian Gulf, It assumes that the seasonal rivers and straits have had a role in bridging the two mentioned areas. The results of this research introduce the study area as an intermediate area for cultural linking between the eastern regions of Jazmourian and Halilrud Basin at Bronze Age and Chalcolithic period.

Introduction
Qal’eh Ganj is located on the most southern part of Kerman province. Chāh-e Khodādād is one of two districts of the present Qal’eh Ganj county, on the border of Sistan & Balouchestan and Hormozgan.
In 2016, the first season of archaeological survey and reconnaissance of county of Qal’eh Ganj has been carried out as a part of the Iranian National Archaeological Map Project in which the authors tried to clarify the cultural status of the region in different periods.
In addition to these purposes, the present research attempts to analyze the results of this research in order to identify regional and trans-regional connections and interactions with the neighboring areas. 
Geographically, this region has a strategic situation because it appears to link three significant cultural zones of southeast of Iran (Mokrān, Persian Gulf and Halīlrūd basin).
This survey resulted in the discovery of 66 archaeological localities dating from Palaeolithic to Islamic periods. The sites are morphologically influenced by the geographical factors of their places that can be categorized into two different types: plain areas and highlands (foothill and mountainous areas). 
Based on the surface data, 39 sites can be assigned to prehistoric times (Bronze Age and Chalcolithic period) matching the cultural sequence of southeastern Iran. Here, we aimed to answer two following questions: 1) what were the patterns of prehistoric settlements in this area? 2) How this area interacted with the other regions of southeastern Iran?   

Data and Materials
In southeastern Iran, our information about the prehistoric times is limited to the old excavations of Iblis and Yahya. Recent excavations in Jiroft (Konar Sandal sites and Varamin), Tepe Vakil Abad in Orzouiyeh, Tepe Dehno in Shahdad have revised our knowledge about the chronology of the region which made us able to form a chronological frame for relative dating of the study area materials.      
Based on this comparative dating, Chalcolithic sites include two periods of fifth and fourth millennium BC including three cultural periods of southeastern Iran. 
In spite of chalcolithic site locating on both of plain and highlands, no Bronze Age site was found in the plain. Bronze Age sites only dispersed on highlands and seasonal river beaches expanding from the southern Jazmurian to northern Persian Gulf shores.
The stone fences and platforms, graves and remains of great stone architectural complexes are the shared elements of all the Bronze Age sites. We can suggest different functions for theses structure including graves, residential spaces and water management systems.
Chronologically, Bronze Age in this area coincides to cultural periods of Yahya IVB and Bampur I-VI in south eastern Iran. Unlike the chalcolithic sites which are located on both plain and highlands, we found no Bronze Age site in the plain, they all were scattered in the highlands.
 
Conclusion 
Based on the relative dating, it is realized that the Chalcolithic settlements date back to fifth and fourth millennium BC presenting three cultural periods of southeastern Iran, respectively Yahya VA, Mahtoutabad I and Aliabad.
Bronze Age sites are dispersed on highlands and seasonal river beaches expanding from the southern Jazmourian to northern Persian Gulf hinterlands.
 Regarding to dispersion of the Bronze Age sites and their strategic locations, the straits and seasonal rivers are considered as the natural corridors to link Jazmurian to the northern bank of Persian Gulf.
Based on the pottery evidence, a cultural continuation is evident from Bronze Age to early second millennium BC. 

Abstract
Bampur historical complex is located in Makran – Jazmourian Basin in a flat plain in the Northwest of Bampur city, the capital of the region and 4 km to the North of Bampur River (20 km to the east of Iranshar). Extensive firing and burnt vestiges are one of the most characteristics phenomena at Bampur Castel. The evidence of firing is scattered nearly all over the site and it is not limited just to spaces like pits or kitchens. The diversity and abundance of brunt materials (seed of cereals, fruit remains, woods, charcoals and mat-made shoes) allowed us to use them for archaeobotanical studies. Due to the limited archaeological excavations especially in prehistoric sites, Iranian Baluchestān has so far been less-known from archaeobotanical and history of vegetation point of view. This research present the results of studies on the plant remains obtained from some pits and firing debris belonged to the Qajar period’s layers. The purpose of the study was to recognize the vegetation around the site and the type of plants used by the inhabitants during that period. Microscopic observations and analyze of 2301 charcoal fragments, woods, seeds, rachis segments and fruit remains showed that the vegetation cover around the Castel included trees such as tamaris, willow, acacia, musquit bean and date palm. They used the wood of these trees to meet their fuel needs (especially tamaris) or as construction materials (willow, acacaia and mesquites). Given the current ecology and geographical distribution of these species, it is reasonable to assume that the identified trees are native to the area and have grown around the Castel. Also the remains of Cereals (wheat and barley), fruits (date palm) and Cucurbits (Watermelon and melon) found in the firing debris testify agricultural activities. In addition, further evidence is attested by the presence of burnt seeds of the wild plants or weedy such as rye, bermuda grass, brome, wild grass, vetch milk, vetch, medic, goosefoot family, knotweed, seepweed, cowherb, asphodel and sedge family (present in the fields along with agricultural products).

Introduction
The study of vegetal remains is not solely limited to climate change that occurs normaly over a long period of time. It could be used for reconstruction of vegetal cover, cultivation patterns or the introduction of non – native species compatible with the environment of a specific region. 
Bampur castel is located, in a flat plain on the northwest side of Bampur city, 4 km north of Bampur River and 20 km east of Iranshahr. The castel have a rectangular – oval shape in the northeast- southwest axis. Due to the best state of conservation at the site, large quantity of vegetal remains including seeds, fruit remains, woods, charcoals and reed mat and other artefcats were found in archaeological contexts. 
The present research will study plant data obtained from the excavated layers in the second season of excavations at Bampur castel conducted by Nozar Heydari in 2018 (heydari 2018). Here, we will try to answer to the following questions: 1. What was the vegetal cover around Bampur in the late Islamic period (Qajar period)? 2. Which kind of woods were used by the inhabitants of the region during that period? 3. What plants species were cultivated by the inhabitants as food resources?
Unfortunately archaeobotanical studies have not been realized in Iranian Baluchestān. Henece, for the first time archaeobotanical studies have been applied to identify the vegetation history of the area, the plant resources and the possible existence of non – native species. The Information on the agriculture and plant economy of Pakistani Baluchestān during the prehistoric times has been available (Tengberg, 1998; 1999; Tengberg & Thiebault, 2003; Costantini, 1981; 1990). However in the Iranian Baluchestān, no specialized study has been conducted in this field. In the southeasten part of the Iranian Plateau and in the Indo-Iranian Borderlands (Sistan, Baluchestān and Kerman) several long-term environmental studies have been carried out in some prehistoric sites by iranian and foreign experts resulted in obtaining valuable information on the history of agriculture and vegetal cover of the area (Costantini & Costantini-Biasini, 1985; Costantini, 1977a-b;  Costantini, 1979; Meadow, 1986; Shirazi & Shirazi, 2012; Tengberg, 2008; Mashkour et al., 2013 ; Vaezi et al., 2019; Hamzeh et al., 2016; Gurjazkaite et al., 2018; Shirazi 2019; Kavosh et al., 2020).

Material and Method
In the second season of excavations a total of six trenches were excavated including:  W1.T2, W1.T3, W1.T4, W1.T5, W1.T6, W1.T7. The archaeobotanical data were obtained from W1.T2, W1.T3, W1.T4, W1.T5. Extensive traces of fire and ashe were scattered all around the castel. Considering the diversity and large quantities of plant remains (grains, fruitstones, charcoals, woods and artefacts) it was decided to select them for archaeobotanical studies. In total, 10 samples from contexts such as pits and fire debris have been collected. From 153 litres of collected debris by water sieving, about 5690 ml. plant remains including seeds, fruitstones and rachis segments were obtainted. Laboratory studies of these data have been done in the Archaeobotanical Laboratory of the World Heritage Site of Shahr-i Sokhta.

Discussion
A total of 310 fragments of charcoal and woods and 1991 seeds, fruit stones and rachis segments were studies. Anthracological digramme indicates the presence of various trees and shrubs such as tamaris (Tamarix spp.), willow (Salix sp.), date palm (Phoenix dactylifera), acacia (Acacia sp.) and mesquites (Prosopis sp.). The relative abundance of tamaris and willow is higher (79%) than other plants. Tropical plants such as acacia and mesquites (15%) and fruits like date palm (6%) are in the second and third ranks respectively. This evidence shows that the inhabitants used the wood of tamaris as fule and willow, acacia and mesquites as construction materials. Given the habitat and geopraphical distribution of the actual vegetation, it is quite reasonable to assume that the identified trees are native to the area.
In addition to the identified trees, carpological digramme indicates the existence of various crops like cultivated cereals  (emmer wheat/Triticum dicoccum), bread wheat /T. aestivum, club wheat /T. compacteum and barley/Hordeum vulgare), fruits and cucurbits (date palm, melon and watermelon), wild grasses (rye, bermuda grass, brome), wild pulses (vetch milk, vetch, medic), and wild plant or weedy (goosefoot family, knotweed, seepweed, cowherb, asphodel and sedge family) that were present in the fields along with agricultural products.

Conclusion
According to our study, plant resources around Bampur includs trees such as tamaris, willow, acacia, date palm and mesquites. Tamaris is the main source of fuel in the region and willow, acacia and mesquites have been used as construction materials (beams for building strengthen). The remains of charcoal and wood of these trees in the explored contexts show that the inhabitants of the castel did not need to import wood from other areas to meet their needs and were completely self-sufficient in this regard. In addition to these tree, which grew naturally in the past as they do today, Baluchestān also enjoyed favorable conditions for cultivation of cereals (emmer wheat, bread wheat, club wheat and barley), cucurbits (melon and water melon) and other fruits especially date palm. 

Abstract
The third millennium BC marked a period of significant cultural, economic, and commercial exchanges between Iran and neighboring regions, including the Indus Valley, Mesopotamia, the Persian Gulf, the Oman Sea, and Central Asia. This article aims to investigate the cultural semiotics and connections between the Bronze Age sites of Southeast Iran, with an emphasis on Shahr-e Sukhteh, Shahdad, and Tepe Yahya. In this research, the seals and seal impressions of sites in the southeast of Iran, including Shahdad and Shahr-e Sukhteh, will be studied and analyzed based on comparative studies with important sites in Central Asia, including Balkh, Merv, Mondigak, Altintepe, Gonor Tepe, Dashlitepe, Tughlaq, and Ordos region. Therefore, in the framework of the signs studied on seals and seal impressions, a suggestion is made that there have been cultural connections between these regions in the Bronze Age. Based on this, the research questions have been raised as follows: What are the similarities between the motifs of pottery and seals? What are the similarities between the cultural artifacts found in the southeastern region of Iran and the Central Asian region? Were the visible similarities connected and serving a common purpose? Knowing the cultural interactions of these societies requires the study of the material evidence left by them. According to the distances between the ancient sites of the third millennium BC, these signs can be the result of a specific and guided thought that appeared in the sites of the eastern half of the Iranian plateau. The transfer of ideas from one place to another has occurred due to extensive commercial connections between societies. This shows that the cultural interactions between Central Asia and the eastern and southeastern regions of Iran and part of the Indo-European culture in the Bronze Age could have originated from common beliefs and ideas.

Introduction
Seals and seal impressions have been obtained from Bronze Age sites in the southeast of Iran, which are comparable to Central Asian seal samples. On many metal seals and the seals impressions, there are patterns that are similar to those created on the pottery of Shahdad, Shahr-e sukhteh and Tepe Yahya. Several theories have been presented about these signs on pottery samples, including their use as the owner’s mark, the potter’s signature or the trade mark of the pottery workshop, and some signs for measuring volume and numerical value. The use of these signs on the seal samples, potteries, containers and human and animal figures in the third millennium BC both individually and in combination as a part of human mentality along with numerous concepts, originated and were drawn.  It seems that some of these signs are same on the pottery that are repeated in the seals, and some of them are similar to the signs from the Proto- Elamite period to the end of the Bronze Age. Markers have created marks with special purpose and thoughts on seals and potteries and have tried to transfer them. The signs could be ownership concepts, rituals and beliefs of the societies of that period. Out of the total number of 400 seals and seal impressions from the studied areas, 206 seals and seal impressions have signs.

History of signs on pottery and seals in the study areas
In many seals of Shahr-e sukhteh and Shahdad, as well as in some study areas of Central Asia, various geometric, animal such as reptiles and birds, plants and human motifs have been found. In addition to motifs, signs can be seen on the seals that are very similar to the signs created on the pottery of Shahdad, Shahr-e sukhteh, Tepe Yahya and other sites, and in some cases, the seal itself is in the form of a sign. Some signs are similar to Proto- Elamite signs, and others are similar to the body parts of gods (hands, feet, and heads). Most of the signs in the Shahr-e Sukhteh are on sherds related to the bottom of dishes and pear-shaped glasses, which were obtained from the layers related to industrial and residential areas, as well as in the surface surveys of the mounds and cemeteries of the city. Most of the signs on the Shahdad pottery are on the intact vessels obtained from the burials. Incised Signs have been seen on the red pottery of Shahdad (Cemetery A)., these signs were created on pieces of hand-made and almost rough pottery in Tepe Yahya. Most of the signs of Tepe Yahya pottery are grooved on the outer body of the vessel and on the upper part of the bottom, and some on the bottom. From Balkh and Marv, signs are placed on the body or under the bottom of bowls and plates. In Altin Tepe, signs on the clay figurines have also been seen, which Mason considers to be comparable to the signs of the Proto- Elamite, Early Sumerian, and Harappan periods. Also, these signs have been seen in the eastern areas of Iranian plateau, Bampur, Baluchistan, Pakistan, and in sites such as Damb Sadat and Quetta, Amri, Balakot and Rahman Dehri in Mundigag in Afghanistan, and some sites of the Chalcolithic period in India. On the seals, in addition to the two key sites of Shahdad and Shahr-e Sukhteh, there are signs from the sites of the northern regions of the Iranian plateau, such as: Tepe Hesar, sites of Central Asia, Turkmenistan, Uzbekistan, northern Afghanistan, many examples of Altin Tepe settlements, in the northern foothills of the Kopet Dagh mountain range and the abandoned oases of Tughlaq and Gonor related to the Margiana culture were found in the desert plains, in the north of Marv city. In addition, signs on the seals were obtained from the mounds related to the South bacteria culture in the vicinity of Balkh city in Afghanistan and Sapali Tepe and Jarkotan in Uzbekistan, related to the Northern Bacteria culture.  Also, many seals have been found from Ordos, with common signs with the main sites of Central Asia and three sites in the southeastern Iran.

The case studies
Out of the total number of 400 seals and seal impressions in Southeastern Iran and Central Asia, 206 seals and seal impressions contain signs. 11 seals and impressions from Shahr-e Sukhteh and 30 seals and impressions from Shahdad have common signs. Based on the study, it has been determined that there are 33 signs common among the seals and pottery of all three sites of Shahr-e Sukhteh, Shahdad and Tepe Yahya. The commonalities of seals sign and the impressions and potteries in the three sites mentioned in the southeastern Iran and also Central Asia sites have been identified. The studied seals belong to the second half of the third millennium BP. Some pottery samples with similar signs seem to belong to the researched time period. The common signs between seals and the impressions and potteries are divided into three groups, including conceptual, geometric and plant groups (rosette, wheat cluster). According to some beliefs, some signs are derived from the organs of the gods. For example, the picture of the great goddess is frequently seen in many prehistoric potteries from Eurasia. The relevance of these signs with the religious cult of the Great Goddess has been spread and proven in a vast land. In this way, some symbols of the cult of the Great Goddess later became proto-writing. According to the beliefs of the people of the region, these signs are symbols of fertility, vitality and security. It can be acknowledged that these signs as a tool have revealed concepts that cannot be expressed in any other way, in other words, it is a transcendent truth that has become in the form of the symbol. Some of the incised signs, with a qualitative connotation, have emerged over time and have adapted to the spirit of truth-seeking in human and have become symbols.

Conclusion
For better understanding, the signs of seals and the impressions are prepared and shown in tables. The studied signs are in the form of simple and broken crosses (right round and left round), concentric circles, spiral patterns, crossed lines, simple circle and signs in the form of T, S, Y, M, W, stepped shapes, Star and many signs that are unclear. Some signs, including plant patterns in the form of rosettes, wheat stalks, are easily recognizable. Sometimes several signs are seen together on the surface of a seal. Comparative and statistical studies have been done on the signs of seals and potteries. The information obtained from the study of seals and the impressions has led to a detailed investigation and analysis of their patterns. After that, it has been concluded that the signs of the study area are classified into three main types: conceptual, geometric, and plant. Part of the cases, according to their characteristics and importance, the seal is created by the artist in the same form as the sign (picture 7). Another part of the signs that have been grooved on the pottery, have been depicted on the seals in the form of one or more signs (picture 6). In some motifs, the symbols of the gods in human form, the form, and organ and body parts of the gods are reminiscent of the common signs on the pottery and seals of all the three sites of Shahdad, Shahr-e Sukhteh, Tepe Yahya and also the Central Asia sites. This can originate from the thought that some of the organs related to the gods have become a sign of the symbol. The way conceptual signs are placed and arranged can induce message transmission; it is suggested that there are probably early writing signs in the study period, which we have not managed to discover the documentation of them. The commonalities between the signs on the pottery and seals of South-eastern Iran with the seals of some regions of Central Asian are as if their creators had common thoughts and at this time, this tradition of marking on seals and pottery became common. In general, and with collective study of these signs, in any case, it can be said that whatever the use of these signs was, it indicates that the sign makers have used the signs as a message to the future generations and have created these signs on a seal and together and sometimes as a set of signs. The spread of the discussed signs on seals and also on pottery can be considered as an expression of cultural influences and interactions between the mentioned regions in the Bronze Age.
