This paper discussed the provenance system characteristics of Yingcheng Formation in Shiwu fault depression by comprehensive analysis of clastic grain combination, heavy minerals combination, sandy conglomerate distribution, dip logging and other materials. The results show that three provenance systems were identified in Shiwu area of Yingcheng Formation. The mother rocks in the northwest provenance system are sedimentary rocks and magmatic rocks, mother rock in northern slope provenance is magmatic rocks and mother rock in eastern slope are magmatic rocks and metamorphic rocks. The forming and distribution of sand bodies in Yingcheng Formation of Shiwu area were jointly controlled by the three provenances all above.
