The main aim of this project is to understand the historical formation of tribal communities, by investigating archeological sites along the middle Euphrates, as well as geological environment and archeological remains in the Bishri regions. For this purpose,we have conducted a geological and environmental survey several times, beginning from the frrst expedition from March 9 to 16, 2007, and after, around Raqqa, located in the middle Euphrates, in the northern part of Syria. In this report, we particularly concentrate on chronological analysis of the archeological sites there and the formation period of the terraces on which the sites are located, by ^<14>C dating with AMS at Nagoya University. During the two main surveys (November 11-20,2007 and April 28-May 05,2008), we have visited the Tell Ghanem al-Ali site, where extensive archeological excavations have been performed at two locations in the northeast side of the Tell, Square-1 (9x9 m^2) and Square-2 (3x15 m^2). We have detected several fragments of pottery as well as black layers composed of charred soil and charcoal fragments. The layers were quite clear and we can believe that these layers have resulted from human activities at the site. We have collected totally 19 samples such as charcoal and wood fragments from a Square-1 trench and adjacent outcrop to the site. We also collected some charcoal and organic soil samples to investigate the formation age of the lowest terrace on which the site is situated. ^<14>C ages for 18 samples related with human habitation at the site are concentrated in a range from 4001±30 BP to 4114±35 BP, and calibrated date from 2850 to 2500 cal BC, for one slgma error. These results are almost consistent with an archeological view on chronology of early bronze-age period estimated based on typological analysis. ^<14>C ages for samples collected from the sediments that formed the lowest terrace ranged from 927±25 to 4494±37 BP. These ages are informational to estimate the formation period of the lowest terrace, but do not perfectly suggest the formation age of the base sediment on which the Tell is located. In conclusion, it is strongly required to excavate the Tell down to the basement and get a suitable sample for ^<14>C dating., 第21回名古屋大学年代測定総合研究センターシンポジウム平成20(2008)年度報告}, pages = {103--111}, title = {シリアTell Ghanem al-Ali遺跡発掘試料及びその周辺地域の段丘堆積物試料の14C年代}, volume = {20}, year = {2009} }
