Provenance system research on Shawan formation of Chunguang block in the western margin of Junggar basin

By studying the lithologic characteristics of clastic rock, framework grains, combination of heavy minerals, seismic attribution and formation dip angles, the provenance system of Shawan formation of Chunguang block in the western margin of Junggar basin has been determined. The research results indicate Zaire Mountain is the source for Shawan formation and there are three directions for providing clastics: northwest, west and northeast. The middle part of Chunguang block is a mixed provenance area and the extension of various provenance systems has been determined through this study.
