Provenance analysis is the most important aspect in the research of ba sins and orogene and is of great significance in studying the relative position, evolution and the interaction of the basins and orogenes. There have been various ways in provenance analysis. The paper has discussed the ways, rules an d limitations of heavy minerals, clastic rock components, fission track, sedimen tary, geochemistry and isotopic methods. It is showen that geochemistry and iso topic methods have the bright and wide uses in the future. Meanwhile, the influence structure and sedimentation such as structure uplift, erosion, chemical weathering on provenan ce can not be neglected. It is worthy to note that reasonable conclusion sho uld be drawn only through the combination of various ways of provenance analysis .
