摘要：

There are 13 kinds of clastic rocks, 14 kinds of lithofacies and seven sedimentary microfacies recognized in the Chang 6 Member of the Yanchang Formation. They indicate a river-lake environment. The vertical variation of sedimentary microfacies from the lower to the upper is shallow lake or prodelta delta front underwater distributary channel or interdistributary bay subaerial distributary channel for Chang 61 and shallow lake or prodelta delta front distal bar mouth bar underwater distributary channel for Chang 62. The trial application of sequence stratigraphy shows that the Chang 6 can be subdivided in sequence stratigraphy. This subdivision can be correlated with the subdivision by sedimentary stratigraphy.
