The Heishishan area lies about 7 km to the southwest of the Baiyinchang Cu-polymetallic orefield, both of them are located in the eastern section of the North Qilian orogenic belt. The study covers four plutons including Haoquangou, Baimawa, Heishishangou and Fangfuya (from south to north). A small epithermal gold deposit and some polymetallic mineralization have found in the Haoquangou and Baimawa plutons , respectively (Fu et al., 2005). That four plutons are closed related to Au mineralization was revealed in exploration. The four granites have been classified based on a rigorous use of mineralogical and geochemical classification schemes in this study. Further detailed geochemical study would determine the economic significance of the studied granitic rocks and allow understanding how the plutons were fit into tectonic setting of the region.
