Abstract: Proper understanding of paleocurrent and source direction in study area at stage of hydrocarbon prospecting is of great significance for the reservoir prediction and the trap evaluation. Fuxian exploration area is located in the southeastern Ordos basin, adjacent to lacustrine sedimentary area of the basin. In recent years, there are some debates about the directions of paleocurrent and sources. There are many kinds of methods for source analysis such as heavy minerals method, sedimentology method and geochemistry method. The heavy mineral analysis method is applied to analyze the characteristics of Yanchang heavy minerals in study area. Combined with the paleocurrent survey data of the outcrops and the regional lithofacies paleogeography feature, it is pointed out that the sediments in this exploration originate from the northeastern Ordos basin and the paleocurrent directions point to the southwest on the whole.
