Abstract
The first season of archaeological survey in Marivan by a team from University of Bu-Ali sina Hamedan was lead to identify some prehistoric sites from Middle Paleolithic to Chalcolithic period. As a result of in mentioned investigation prehistoric cultural sequence of the area from Middle Paleolithic to Middle Chalcolithic period (except Late Neolithic and Early Chalcolithic) have been identified. So, there was a main question about the absence of Late Neolithic and Early Chalcolithic period sites of Marivan area. Fortunately, during our recent archaeological survey in Marivan, we succeeded in discovering an interesting site (Qala Ziwa) which has traces Late Neolithic and Early Chalcolithic (J ware). In addition to Late Neolithic and Early Chalcolithic (J ware), some typical Dalma related pottery was also sampled from the site. Among mentioned potteries, we believe that most important period can be considered as Early Chalcolithic period. Against other regions of Western Iran particularly Central Zagros that many Early Chalcolithic period sites were identified, this area is really less known and obviously Qala Ziwa is one of the first Early Chalcolithic period site ever reported from Marivan area. This site has typical J ware and compared with similar Early Chalcolithic period sites in Central Zagros. This pottery has been related to the Western parts of Central Zagros like Mahidasht zone and discovering J ware in Marivan can added this area to the distribution zone of this culture also. As mentioned, surface survey of the site showing that Qala Ziwa has a complete sequence from Late Neolithic to Middle Chalcolithic period. So, excavation of the site in order to clarifying stratigraphy of the site would yield valuable information regarding too late six millennium B.C archaeological studies of Western Iran.

Introduction
Looking to the geographical position of Marivan area, it became clear that this region is placed between 2 of the main archaeological zone of entire Western Iran (Central Zagros in South and Urmia lake basin in North). Prehistoric Archaeologist studies concentrated at those 2 mentioned zone and did not pay attention to the prehistoric sites (particularly Neolithic period) of studied (Marivan and adjacent areas). Fortunately, the situation has changed recently and a few Neolithic period sites have been reported not only in Marivan but at the areas like Bijar region (Motarjem & Sharifi, 2018). For the first time was identified 2 Neolithic sites in 2002 (Mohammadifar & Motarjem, 2003, 2015). Two Marivan Neolithic period sites (Tepe Hamaomin and Hamamorad) dating to early period of Neolithic (Mohammadifar & Motarjem, 2003, 2015) and as mentioned, there was not any information about Late Neolithic and Early Chalcolithic period sites of the area. Noted that as result of first archaeology survey of Marivan by Bu – Ali sina university expedition some sites from Middle Paleolithic to Middle Chalcolithic period (except Late Neolithic and Early Chalcolithic sites) reported. So, there was this important question that what happened after Early Neolithic period in Marivan region and why no Late Neolithic and Early Chalcolithic site was reported? Why there is such long gap time (more than 3 millinume) in this area? Discovering Qala Ziwa which contain cultural deposits from Late Neolithic and Early Chalcolithic is may fill this cultural gap obviously.

Methodology
The research methodology uses in this study is based on primary surface survey. Regarding to the importance of the site for late 6 millennium B.C archaeological studies, the site was surveyed carefully and from each periods typical pottery was sampled. As common in archaeological studies the sampled potteries have been sorted, photographed and analyzed. Our preliminary analyzes showing that this site has 3 different archaeological deposits: Late Neolithic (?), Early Chalcolithic, and early phase of Middle Chalcolithic period (Dalma phase). Any way future studies and even excavation would tell us more about this interesting site. 

Conclusion
Even as result human interference like agricultural activity the surface of the site was damaged, and it is not possible to sample data systematically, but distribution pattern of surface pottery was really interesting. As mentioned, surface pottery showing that the site would contain the deposits of 3 different archaeological periods:  Late Neolithic (?), Early Chalcolithic, and early phase of Middle Chalcolithic period (Dalma phase). The pottery of last period (Dalma phase) scattered at the highest level of Tepe, J ware was sampled in Middle part and   Late Neolithic shreds distributed at the lowest level of the site. Even such surface observation is not so trusted and archaeological excavation may show something different, but this pattern is really similar the stratigraphy of some Central Zagros sites like Seabed and Chogha Maran. In Chogha Maran the Early Chalcolithic deposits characterized by J ware lay on the virgin soil and Middle Chalcolithic is the upper one. In Siabid the most ancient cultural deposits belonging to Late Neolithic period which Early Chalcolithic (J ware) and Middle Chalcolithic are upper layers. But in some other site like recent excavated site like Tepe Qeshlagh in Bijar the situation is completely different. In Tepe Qeshlagh the most ancient layer is Late Neolithic deposit which upper layer is Dalma phase. But as mentioned in Tepe Qala Ziwa and some other Central Zagros sites, J ware would place between Late Neolithic layer and early phase of Middle Chalcolithic period (Dalma period). All mentioned document demonstrated that this new discovered site can be compare with Central Zagros region and particularly Western part like Mahidasht zone. As mentioned there was not any information about Late Neolithic and Early Chalcolithic period of this area of Western Iran and Qala Ziwa is one of the first discovered site of this period. Obviously, future archaeological survey and excavation would yield remarkable information about archaeology of late six millennium B.C of Western Iran. 

Abstract
Spindle Whorls are among the main cultural materials and needs of animal husbandry and semi-”frozen” societies and are among the works that are directly related to the pattern of livelihood and production in the clothing family and fibers of early societies. to be. Which are interpreted in the analysis of the findings of ancient sites. The area behind Malayer Plain Poshteh-Forodgah Tepe is no exception to this feature, and the number of 123 Spindle Whorls found among its archaeological excavation findings has a significant presence in terms of type and f. The main stones of this area can be divided into two groups: convex and conical, each of which is divided into two sub-branches: painted and simple, and in terms of quality of construction, they can be divided into two groups: medium and Roughly divided. All Spindle Whorls are made of baked clay with a mixture of herbs and in different sizes. The purpose of this research is in the first stage, typology and study of saddles and in the second stage, analysis of livelihood model related to the production of textiles in the hills posht forodgah. A significant number of Poshteh-Forodgah Tepe and its application in the production of yarn by analyzing it on the produced fibers and how to organize this production can help a lot. The method of the present research, based on comparative studies and with a descriptive-analytical approach, seeks to answer these questions: What kind and forms of hymns discovered Poshteh-Forodgah Tepe and what threads are used in its production? Given the Semi-Unilateral of the Tepe communities Poshteh-Forodgah Tepe and the abundance of Sardok, the production of textiles in this area has been for local and domestic use and trans-regional trade? Considering the Semi-Unilateral and nomadic settlement and the method of economic production based on animal husbandry in the early communities of the Central Zagros and the hills Poshteh-Forodgah Tepe, it seems that based on the variety of mounds in type of material, quality of species, shape and size, these wool fibers They are mainly used for local use and trade outside the region to meet basic needs.

Introduction
Spindle Whorl is a cultural object and cultural material that is mainly made of stone, bone, wood, etc., which provides the first manifestations and old evidence from different stages of fabric production.
Analysis and typology of Spindle Whorls provide good information on how ancient tissues rotate, but it is necessary to establish a methodological typology of this type of ancient cultural finds. Type and packaging in type, shape and size provide an effective way to determine how yarns work. The shape, type and appearance of each yarn is directly related to the type of production, spinning. Therefore, the appearance and functional typologies of saddles are other ways of knowing the type of spinning and other stages of textile production. For example, the typology, shape and function of a highly effective method of the characteristics of the fibers produced and used and the final product produced from yarn or fibers (such as: wool, silk, fabric, etc.) are presented through rotation in the production of clothing. Gives. Among these, the “weight” of Spindle Whorls is considered as one of the most important factors determining the properties of production fibers. Among these, the “weight” of Spindle Whorls is considered as one of the most important factors determining the properties of production fibers. Finally, sawdust should be placed in significant categories that determine spinning and textile production, and these categories are based on the characteristics that determine the use of sawdust. Spindle Whorls discovered from the Poshteh-Forodgah Tepe The most abundant cultural finds in the hills behind the Poshteh-Forodgah Tepe after pottery are all kinds of Spindle Whorls. These chestnuts come in a variety of shapes and sizes, from circular and semi-circular to conical, all made of fine-grained clay and then heated. The Spindle Whorls of the hills behind the polished Poshteh-Forodgah Tepe, in terms of simple appearance, is less decorated and less decorated. Alone and on some of them, a linear and crescent-shaped dimple (or a kind of sign and symbol) can be seen, which is apparently created with nails. The Spindle Whorl have a hole in the middle for the passage and the wooden handle to rotate. The central hole of the Spindle Whorl is usually made in such a way that it is narrower at one end to prevent the movement of the wooden rod that was placed in this hole. And the thread was twisted around it; However, some cases of Spindle Whorls have been obtained from this area that did not have holes. It seems that the process of making these Spindle Whorls is incomplete and due to the similarity of Spindle Whorls, they can not be classified as Token or counting objects. It should be noted that no stones were found on the slopes of the Poshteh-Forodgah Tepe From all the new Neolithic stages to the Old Copper Age and the Stone Age of the Poshteh-Forodgah Tepe, three main types of oval, pyramidal and conical shapes have been obtained. These Spindle Whorls do not have the desired construction quality in the lower layers (new Neolithic of phase c). Because it is deformed and rough in appearance, and in terms of cooking, it gets a little hot and a kind of raw hand can be seen in making them. With the development of higher stages and the age of copper and old stone, Spindle Whorls have advanced in terms of variety and quality in terms of construction and have gained high resistance.
These heads vary in weight. The lightest Spindle Whorls weigh about 5 grams and the heaviest Spindle Whorls discovered from this hill weigh about 160 grams. From this point of view, it can be said that the production of yarn and the use of fibers in this region also have a diameter. Produced from the thinnest yarn to the thickest. As mentioned, the weight and diameter of the saddle circle is the most important determining factor in the process of spinning and yarn production, which is one of the important features among Poshteh-Forodgah Tepe saddles. What can be said about the diameter and size of Spindle Whorls in this area? In order to increase the diameter of the rotating shaft with the light weight of the saddle, the hollow feature of the saddle has been used so that the weight of the saddle does not increase. This feature (in the emptiness of the saddles) is one of the examples of the ridges of Qalangap hill (Abdollahi and Sardari Zarchi Figure 14, 130: 1392) and Chaghamish... and Tal Bakun (Alizadeh 1382: 349, (Figure 9) is also considered and large and hollow Spindle Whorls are produced to produce the weight of thin fibers with high flexibility and elasticity.
Poshteh-Forodgah Tepe headboards are made in the simplest possible way in terms of decoration, and the least amount of decoration is seen in terms of design compared to other areas, and only a few examples of designs are created compactly (Figure 7). The simple-edged conical saddle, which is also one of the most common types of saddles, is similar to the conical specimens of the Tel Bakun, which in some cases have compact linear or circular shapes (Alizadeh 2004: 146 and 349)

Conclusion
Using a comprehensive comparative method, 123 Spindle Whorls obtained from a season of excavation at the Malayer Plain Poshteh-Forodgah Tepe were discussed in response to questions:
In response to the first question, in addition to a coherent typology, this type of cultural findings (based on compatibility with Spindle Whorl of Charo, Chaghamish, Tal Bakun and Qalagap regions) were identified in 6 species.
The heads of this region are divided into two main groups: convex (oval and two-sided pyramid) and conical (one-sided and cylindrical pyramid).
Each group is divided into two subgroups, carved and simple, and in terms of construction quality, they are in two groups, medium and rough.
All chests are made of clay with vegetable chamotte and in different sizes (2 to 5 cm and weighing 5 to 160 grams). Some heads have pressure patterns created by a sharp tool. Depending on the type of semi-resident settlement and the method of economic production based on herding (sheep and goats) in the early communities of Central Zagros and also the Poshteh-Forodgah Tepe area due to the high volume of goat bones (due to jaws and horns) based on the variety of Spindle Whorls in this area In terms of shape, size and weight of the species, these Spindle Whorls are mostly used in fleece fibers.
Accordingly, heavy and long Spindle Whorls with high rotation axis are used to twist thick and long fibers (goat hair) and small short Spindle Whorls with low rotation axis are used to twist thin and short fibers (fleece) with different thicknesses. In this study, Spindle Whorls weight was considered as test variables on yarn diameter, yarn rupture and elasticity and yarn warp.
In response to the second question, considering the semi-monolithic location of the Poshteh-Forodgah Tepe based on various ash deposits to a depth of about 160 cm and the vertical migration approach of the communities present in it, it seems that most textile products are for endogenous use and sometimes for trade. It has been trans-regional in meeting basic needs.

In the prehistory of western Iran, from the Late Neolithic to the end of the Chalcolithic period, there are some red-slipped potteries that continued to exist with minimal or even without any changes, despite the change in periods and the subsequent change in pottery styles and traditions. This has led to ambiguities and errors in distinguishing these types, and as a result, incorrect identification of the cultural periods of some sites of the Late Neolithic period, especially the Chalcolithic period. Are the red-slipped potteries of the Neolithic period to the end of the Chalcolithic period in western Iran really a special type of pottery that continued to exist without any changes despite the changes of cultural periods? What are the differences between the red-coated potteries of the Neolithic period and the Chalcolithic period? The failure of some researchers to distinguish the Red-Slipped potteries of the Neolithic and Chalcolithic periods creates the assumption that these types of pottery are not mutually exclusive. The present article, using an analytical-comparative method, attempts to answer the questions and hypotheses raised by closely examining the Red-Slipped potteries obtained from the excavations of some significant sites of the Late Neolithic and the Chalcolithic period in the western regions of Iran, such as Siahbid, Genail, Ghazanchi, Saha Chai Tepe, and Tepe Gheshlagh. The results of this research show that although there are undeniable similarities at first glance between the Red-Slipped potteries of the Late Neolithic period to the end of Chalcolithic, there are subtle differences in the form of the pottery, the degree of firing, temper, and the type and color of the coating, which a careful study will help distinguish the pottery of the mentioned periods from each other. The findings of this research show that the Red-Slipped potteries of the Late Neolithic period has burnished slip, a feature that is not seen in the later period, especially in the J and Dalma period. Also, in the late Chalcolithic period, in addition to changes in the color of the pottery’s coating, carved decorations are seen on the outer body of red pottery, which has not been reported for Red-Slipped potteries from previous periods.
