贵州盘县大洞的堆积物 ,自上而下可以分为 3层。大洞主体堆积物为角砾堆积 ,来源于洞顶灰岩的崩塌 ,另外有人类遗物以及洞外片流作用带入的泥砂。人类化石、旧石器和哺乳动物化石主要分布在第 2层角砾堆积中。堆积物在洞厅各部位均有相应分布 ,属同一沉积序列。已知的早期人类活动时间大约从2 60ka .B .P .开始 ,到 142ka .B .P .前后结束 ,对应于深海氧同位素的第 6、7阶段。角砾层下段 ,发育一套遭强烈溶蚀和风化的堆积物 ,地球化学分析结果显示其湿热的沉积环境 ,时间大约在 2 60— 180kaB .P .期间 ,对应于深海氧同位素第 7阶段 ;大洞堆积物在气候变化周期上与黄土、青藏高原冰期序列可以对比
Guizhou Daxian Daxong deposits, top-down can be divided into three layers. The bulk of the main body of the cave is a pile brecciation, which is caused by the collapse of the limestone in the top of the cave. In addition, there are human remains as well as sediment brought into the water by the extra-cavity flow. Human fossils, Paleolithic and mammalian fossils are mainly found in the second-level breccia accumulation. Accumulation in the cave hall has a corresponding distribution of all parts, belong to the same sedimentary sequence. Known early human activity time begins approximately from 260 K.B.P. and ends before and after 142 K.B.P., corresponding to stages 6 and 7 of the deep-sea oxygen isotope. In the lower part of the breccia, a set of strongly eroded and weathered sediments are developed. Geochemical analysis shows that the hydrothermal depositional environment is in the range of about 2 60-180 ka BP, corresponding to the 7th stage of the deep-sea oxygen isotope. The sediments can be compared with the sequences of loess and Qinghai-Tibet Plateau during the climate change cycle
