Abstract: The paper discusses the clay mineral distribution and evolution of argillaceous rock in sedimentary basins from view of tectonicgeology. It's considered that tectonic backgrounds and movements are the basical factors controlling clay minerals of argillaceousrocks in sedimentary basins. This explains more reasonably the differences of clay mineral compositional characteristics of argilla-ceous rocks between petroleum basins in the east and west China. Furthermore, it explains a special kind of clay mineral assem-blage generally existed in western Tertiary argillaccous rocks, in which the clay minerals are mainly composed of illite and chloritebut the diagenetic grade is very low.
