摘要
On the basis of the rock assemblage, Nenjiang Formation can be divided into three members, alternate layer of the black mudrock(shale)and silt mudrock in the lower member, alternate layer of the gray-green silt mudrock, argillaceous siltite and fine sand in the middle member and alternate layer of the motley silt mudrock in the upper member. After the synthetical characteristics of the rock are analyzed, the evolution process of Nenjiang Formation is deduced from bottom to top, i. e. , alternation change of semi-deep lake, deep lake and semi-deep lake(shallow lake)facies, shore lake(beach lake)facies in the last.
