Studying the evolution of depositional environments is essential to the comprehensive understanding of the living conditions of ancient populations. To reconstruct the depositional environment at Shuidonggou, we carried out archaeological excavations and collected systematic deposition samples at the key position of Shuidonggou Locality 2 for grain size analysis and sporopollen statistics. The environmental evolution around the Shuidonggou site generally underwent four stages at ~72-18 kaBP. During the first stage （~72-41 kaBP）, the river developed with gravel and sand stratums. During the second stage （41-34 kaBP）, a swamp with numerous aquatic plants formed. In the third stage （34-29 kaBP）, site formation was characterized by shallow lake depositional conditions; the climate was relatively warm and humid. The marginal bank depositional conditions deteriorated during the fourth stage （29-18 kaBP）, and the site underwent several dry events; the climate also became drier and colder.展开更多

More luminescence and AMS 14C dating in laboratory show that Paleolithic culture develops during the Upper Paleolithic period with ages of 35―20 ka. The Paleolithic culture of SDG 1 is a little earlier than that of SDG 2 similar to SDG 7. The sandy sediments on terrace Ⅱ of Biangou River deposits in the past 72―18 ka, corresponding to Last Glacial. SDG2 has a stable sedimentary environment, resulting in the continuous stratigraphy, thickest deposits and rich environment and culture information, which can be regarded as the important and classic paleoanthropological section of Late Pleistocene in this region.展开更多
