 note = {As a part of research project “ Formation of Tribal Communities: Integrated Research in the Middle Euphrates， Syria", we have conducted a geological and environmental field survey in the Bishri region, southeast of Raqqa, Syria. 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, for the first time from March 9 to 16, 2007, around Raqqa, located in the middle Euphrates, in the northem part of Syria. During the survey, we have visited two archeological sites, mainly used during Early Bronze Age, as suggested by Japanese archeologists who are conducting archeological survey on these sites. At the Tell Hammadin site, we have focused on a pit (ca. 1.5m high) that might have been illegally excavated by robbers. 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 resu1ted from human activities at the site. We have collected five charcoal samples there. ln addition, we have dug a small hole at Tell Ghanem al Ali site, and collected a small fragment of charcoal. Two of charcoal samples from Tell Hammadin were ^<14>C dated with AMS at Nagoya University, Japan. ^<14>C dates were obtained consistently with each other as 3915±35 BP and 3963±34 BP. Calibrated dates from the two ^<14>C ages ranged 2570-2460 cal BC and 2470-2350 cal BC, respectively, in one sigma error. Though the number of analyzed samples is only two, we may suggest that habitants with pottery of early bronze-age period dwelled at Tell Hammadin at around 2570-2350 cal BP. Concerning about this experimental result, one of the authors, T. K., an archeologist, have commented that this result is quite consistent with his view on chronology based on typological analysis on pottery fragments collected during the surface survey of pottery fragments on the site.},
