摘要
2014年7-8月在河北怀来盆地开展的旧石器考古调查工作新发现确认10处旧石器地点,获得20余件石制品及动物化石。石制品类型包括石核、石片、工具以及断块,总体来看包含了石片石器技术和细石叶技术两套技术组合。石制品原料以火山岩为主,应为就地取材;石核剥片与工具修理均主要采用锤击法。永定河两岸第二、三级阶地是文化遗物埋藏的主要地貌部位,依相关地貌、地层资料以及石制品的类型特征,初步推测新地点的时代主要为中、晚更新世。
This report presents the preliminary result of a Palaeolithic survey in Huailai basin, Hebei Province conducted by the Institute of Nihewan Archaeology of Hebei Normal University and the Huailai Museum. A total of 10 Palaeolithic localities, mainly locating along the southwest bank of Guanting reservoir, were newly discovered and confirmed, and more than 20 stone artifacts and a few mammalian fossils were collected. Based on the technological and typological characteristics of these stone artifacts, two different groups of lithic artifacts have been identified, one is a flake-tool based assemblage characterized by simple cores, flakes, lightly-retouched tools etc.; the other is a microblade assemblage characterized by wedge-shaped microblade cores. Dominated by volcanic rocks, raw materials for stone knapping were mainly collected as pebbles from nearby riverbeds. The principal flaking and retouching technique was direct hard hammer percussion, while soft hammer had probably also been used when modifying biracial preforms of wedge-shaped microblade cores The Palaeolithic remains are mainly buried in the second and third terraces of both banks of the Yongding River. It could be inferred from the geomorphological and stratigraphic comparisons in the drainage basin of the Yongding River valley that the newly discovered localities may be dated to the Middle and Late Pleistocene, and the date of microlithic materials is more likely the end of the Late Pleistocene based on the comparison with the similar finds in the Nihewan basin
