摘要

 
    

In order to clarify the distributional feature of provenance and depositional systems of the second Member of Shahejie Formation in Qikou Sag, the surrounding provenances and their respective influence scopes on the deposition have been systematically studied by means of multi-parameter analysis, such as detrital composition, heavy minerals, rare earth elements. The study indicates each parent rock type is mainly medium-basic eruptive rock. Distributary provenances, specifically Gangxian, Gangdong, Zhaobei and Zhangdong, only control nearby fan deltas and beach bar deposits. In general, the provenance has a good allocating relationship with the depositional system, which provides a material base for the formation of lithologic stratigraphic reservoir of the second Member of Shahejie Formation.
