Abstract: The Shan–2 member of Shanxi Formation in the eastern margin of Ordos basin has excellent source reservoir allocation conditions, and is an important reservoir for regional oil and gas exploration. Based on the outcrop paleocurrent, heavy minerals and clastic zircon dating data, the provenance analysis of Shan–2 member in Daning−Jixian exploration area is carried out, and it is considered that the Daning−Jixian oil and gas exploration area in Shan–2 member sedimentary period is jointly controlled by the south and north provenances. The main evidence is as follows. ① There has been a significant change in the ancient flow direction of sandstone in the outcrop area of the eastern part of Daning−Jixian. Guantou Town, Linfen City, in the north, is characterized by a north to south ancient flow direction, while Taitou Town, in the south, is characterized by a south to north ancient flow direction. ② There is a significant difference in the heavy minerals of sandstone in the Shan–2 sub section of the Daning−Jixian oil and gas exploration area. Taking the vicinity of the Erlang mountain tourist area as a boundary, there is a significant north−south differentiation in the ultra stable heavy mineral zircon and stable heavy mineral perovskite. ③ The peak ages of zircon samples in the Daning–Jixian exploration area are not uniform in the north and south. The zircon ages of sandstone in the north show two peak ages (1 800～2 000 Ma, 2 400～2 500 Ma ), while the zircon ages of sandstone in the south show four peak ages (300～700 Ma, 1 100～1 200 Ma, 1 800～2 000 Ma, 2 400～2 600 Ma). This understanding will not only provide guiding clues for the distribution and characterization of sand bodies in Daning−Jixian oil and gas exploration area, but also provide important evidence for the study of the paleogeographic background of the sedimentary period of Shan2 member.
