Abstract
The Kazeron County is located in the West of Fars Province and 732 M above sea level. From identified sites in survey of Kazeron plane (that mainly are sites of Neolithic period to late of Bronze Age) in total of 141 pieces of stone tools were gathered from 13 sites. Based on research on stone tools, sites as SK023 are show extraction and use / maintenance / repair. In these sites, the existence of core stone indicates of the construction of tools, and also existence a lot of the stone tools are indicates of settlement long-term in these sites. The core stones in all sites are exclusively chipped stone and mostly from kind of Chert stone of gray – green. It seems, produce of tools from other types of Chert stones such as red Chert, Chert of brown stripes, cream Chert, and… have been made in another place. The blades and their flakes in some sites of Kazeron plane (especially sites of SK022 and SK023) represents are the use of these tools for reaping of the plants. The raw material used to make stone tools (that often made of local stone) today it is easily accessible in the Kazeron mountains. These tools, to form of a combination and with natural resins such as bitumen have been placed inside the bone handle or in newer periods inside the metal handle, and similar to sickle have been used to cut plants. From of the main goals of the present research, study of technology diversity in stone tools sites of prehistory in Kazeron plane is for regional and comparative studies and for gain of general knowledge the prehistory of Kazeron plane.

Introduction
The Kazeron County is located in the west of Fars Province and 732 M above sea level. This County from the north to Mamasani and Behbahan, from east and northeast to Shiraz, from southwest and west to part of Borazjan city and Bosher, and from southeast to Firozabad is limited. This County in terms of geographic is located in mountainous area and with surrounded by high mountains. The mountains of Kazeron area is stretched from the northwest to the southeast (Mozafariyan, 1994: 25). The Mountains of Kazeron consists of two ranges and Kazeron plane is between these two mountain ranges. The Kazeron County has a warm climate. The temperature of this county is max.49 degrees above zero and at least 6 degrees below zero. The average rainfall in Kazeron County in years of low rainfall is less than 500 mm and in the rainy years approximately 700 mm (Behrozi, 1968: 8). The Kazeron County has abundant water resources. Abundant springs and a lot of water has a created several rivers. The major rivers of this county are include of Jareh, Shapor, and also freshwater Lake of Parishan (Hatami, 2006: 12). So, Kazeron plane with a lot of water resources and suitable climate had a good environment for development of human societies in the long term. In this research, stone tools related to Neolithic period to Iron Age (that collected from survey of archeology Kazeron plane) have done typology and classification. So, from of the main goals of the present research, study of technology diversity in stone tools sites of prehistory in Kazeron plane is for regional and comparative studies and for gain of general knowledge the prehistory of Kazeron plane.

Research findings
From identified sites in survey of Kazeron plane (that mainly are sites of Neolithic period to late of Bronze Age) in total of 141 pieces of stone tools were gathered from 13 sites. Tepe Qalat 2 (SK002) is located 1 km northeast of Baladeh city. From this site was obtained only 2 chips. A piece is Retouch and another Burin. The Galeh Narenji (SK006) is located in near of the village of Galeh Narenji and 1.5 km east of Pershian Lake. From this site 6 pieces stone tools have been collected. Tal Siah 1 (SK013) another from sites, that is located in around Pershian Lake. From this site 3 pieces stone tools have been collected. Another from sites is Tal Siah 2 (SK014), that from this site 7 pieces stone tools have been collected. Gabrestan Karai (SK015) is located 500 meters southeast of Karai village, and from this site 11 pieces stone tools have been collected. Another from sites this study is Dreh Tampoi (SK016) that from this site 12 pieces stone tools have been collected. Tal Zirakan is located 1 km east of Kaskan village and in south of the Kazeron city. From this site 17 pieces stone tools have been collected. Another from sites this study is Tal Rashton (SK020) that from this site 8 pieces stone tools have been collected. Tal Panj Mahal (SK022) is located 700 m west of Shapro River, that from this site 25 pieces stone tools have been collected. Tal Dehdaran (SK023) is located on the northern margin of Kazeron plain, that from this site 26 pieces stone tools have been collected.

Conclusion
Usually, estimate the ratio of blank flake to core stones can help us to guess that production of stone tools has done elsewhere. On the other hand, the blades and their flakes in some sites of Kazeron plane (especially sites of SK022 and SK023) represents are the use of these tools for reaping of the plants. In general, in spite of a lot of variety in the collection of stone tools in sites of Kazeron plane (that shows diverse and advanced industries), in core stones can’t be seen complexity and advanced technology. Ultimately should be noted, based on survey results and pottery samples, these stone tools are belonging to the 7th millennium B.C. to the end of the second millennium B.C..
