到层序9沉积末期，沉积环境由湖沼相过渡为河流相。 - The time corresponding to the four parts along the section are as follows : the top lake - swamp sediments : holocene ; the uppart fine sand : later late pleistocene ; the middlepart sandy clay : middle - early late pleistocene ; the lowpart clayer silt : later - middle - pleistocene . the fossils and stone artifacts found in salawusu site should be formed during the last but one glacier , its age range is about 0 . 13 - 0 . 19 ma , and belongs to later middle - pleistocene
分析q曲线与氧同位素曲线的一致性以及以上研究结果，包含萨拉乌苏地层的这套沉积物的沉积时代为：顶部湖沼相沉积物：全新世；上部具交错层理的细砂：晚更新世晚期；中部粉砂质粘土：晚更新世中期至早期；下部粘土质粉砂：中更新世晚期。 - Three sets of source rocks had been formed juring the steady sinking of the basin . the first source rock , being clay and calcium clay stone in tiemulike formation of permian was formed in deep lake environment ; the second source rock , being clay stone in xiaoquangou group of middle to upper triassic was formed in the offshore and the shallow lake environment ; and the third source rock , being coal beds in badaowan formation of lower jurassic was formed in the lake - swamp environment . the first one is the most potential , since it has the biggest thickness , the highest organic matter abundance , high maturity and the highest hydrogen generating capacity
