Abstract

The formation made in Pleistocene in the area of Middle and Upper Youngsan river region is found mainly paleosols. It is found through analysis of volcanic ash, terrace and OSL age measurement that the age of paleosol is 12,000-125,000 years ago. As the result of the absolute dating of the second cultural layer of Dangga site(middle of Jiseok river), this region has three cultural layer, lst layer is dated by 70-80kyr., 2nd layer -40-50kyr., and 3rd layer -30kyr. These chronological data is closely related with Whasun Sachang site. According to the analysis of volcanic ash for Chongok and Sachang site, AT tephra is located in the uppermost part of the layers under the first soil wedge. This research represent distribution of Paleolithic sites in Middle and Upper Youngsan river basin. There are 36 Paleolithic sites with six excavated sites. Most of all of them are located in the both side of terraces in the Jiseok river. General techno-typological character belongs to the 'Pebble Tool Tradition in Northeast Asia'. Conclusionally, we can construct the chronology of the Youngsan river region. First peopling of this river came to the Middle Paleolithic period(70-80kyr), such as 1 cultural layer of Dangga and Chipyengdong site with heavy weight tools. The second is related with the transition period of the Middle to Upper Paleolithic, such as the 2nd layer of Dangga, Dosan and lowest layer Sachang site(40-50kyr.). Third peopling is migrated to the river about 30kyr.(3rd cultural layer of Dangga, 2nd layer of Sachang site and Chongok site). The techno-typological character of stone tool represented the flake tool tradition with the trial of the blade tool technique(increase of flake tools with delicate retouch) and widely spread bifacial technique. Finally, Paleolithic people came to this region in the late Upper Paleolithic in the uppermost cultural layer in Sachang site with the microblade culture.
