针对金湖凹陷西斜坡物源方向存在分歧等问题，通过对金湖凹陷西斜坡阜宁组二段第三亚段（E1f2^3）沉积相、重矿物组份特征及分布等研究，对物源方向进行再认识。研究区E1f2^3发育一套外源滨浅湖沉积体系，包括两种亚相、七种微相，亚相为滨湖亚相和浅湖亚相，微相包括滨湖砂坝、滨湖砂滩、原生补给水道、改造补给水道、浅湖泥湾等。通过重矿物直方图分析，认为E1f2^3物源分别来自西部的建湖隆起和西南部的张八岭隆起，其主物源为张八岭隆起，北部和西部的局部地区有少量西部和北部的建湖隆起物源供给。

For the problem of the provenance direction of the second member of Funing Formation（E1f2^3） in the west slope of Jinhu Sag,the source direction of the research area E1f2^3 was reinterpreted by some research results including the sedimentary microfacies and the distribution and characteristic of the heavy minerals. In the research area E1f2^3, there is a shore - shallow lake sedimentary having external source,which contains two kinds of subfacies （ shore lake facies and shallow lake facies） and seven kinds of microfacies （sand bar, sand beach,primary feeder channel,modified feeder channel and shallow bay）. According to the analysis of the heavy mineral histogram,it is thought that the provenance of the E1f2^3 comes from the Jianhu uplift and Zhangbaling uplift, and mainly from Zhangbaling uplift, and only smally from Jianhu uplift in the west and north.
