Abstract: For determining the distribution pattern of the depositional system of Yanchang Formation in the south of Ordos basin , the authors did a systematic research on the provenance and the characteristics of the mother rock by many methods such as the analysis of rocks and minerals , heavy mineral analysis, rock fragment character, geochemical and seismic profile anlysis etc. . The results indicate that there is mainly controlled by three great sediment source regions in the south of Ordos basin, and more detailed divide five subsources, which are from northeast, north, west, southwest and south. Provenance have favorable spatial combination with depositional system and determine the depositional system pattern of Chang6 oilbearing. Provenance is useful to reasonable deployment of oil gas exploration.
