| Abstract: | The spatial distribution of Indo-Chinese and Yanshan Epoch granites in Beishan area of Gansu Province are summarized in combination with the features of some typical deposits which metallogenesis are relevant to these granites. The metallogenesis, tectonic environment, the control of source beds to Mesozoic ore-forming, and the mineralization concentrated areas are discussed. It is supposed that the most of mineralization concentration areas distribute in such areas where the convergences of EW rifts and NE... |
