The Research on Sequence Stratigraphy of Shahezi Formation in Xujiaweizi Depression

Article Preview

Abstract:

By using the data of core, geological log and seism and the theory of sedimentology and sequence stratigraphy , the sequence of Shahezi formation in Xujiaweizi depression are divided into five third-order sequence, they are SQ1, SQ2, SQ3, SQ4 and SQ5 up towards. The range of SQ1 is limited, influenced by palaeogeomorphology. SQ5 are greatly influenced by the late sedimentary denudation, now only in the northwest of the study area can be seen, other part is missing in this layer. SQ1, SQ2, SQ3 are onlap filled. There are defective area in SQ4 and SQ5.
