论华北旧石器晚期遗址的分布、埋藏以及地质时代问题

DISTRIBUTION AND BURYING OF LATE PALEOLITHIC CULTURE IN NORTH CHINA

我国华北地区旧石器晚期遗址及文化遗物通常埋藏于河流的第二级阶地中,地质时代为晚更新世中、晚期。峙峪等遗址的地层清晰、化石丰富、时代明确,没有再搬运的任何迹象。研究旧石器文化必须结合地层、地貌和古生物资料进行综合分析,有适当的年龄数据印证,才能得出断代上的合乎逻辑的结论。

Three main types of continental sediments of Late Pleistocene can be recognized in North China: the cave deposits, the alluvial-lacustrine deposits and loess. More than two hundred mammalian fossil localities of Late Pleistocene and Late Paleolithic Sites have been investigated and excavated in recent years. The occurrence of Late Paleolithic Sites and mammalian fossils of Late Pleistocene seem to be corresponded to the stratigraphy, lithology, geomorphology and taphonomy. Artifacts and fossils are often discovered in:(1) the middle or lower part of the second terrace of local river and its tributaries;(2) the orangish sand-gravel and blackish sandy clay of alluvial-lacustrine deposits;(3) the bottom of gravel under the Malan loess in the loess plateau;(4) the piedmont of hill which stretches into the alluvial basin or plain.
