| Abstract: | Medium-sized and large-scale skarn Cu-Mo-W(Au)deposits,e.g.Nuri,Mingze,Kelu,Chongmuda and Chenba,are distributed in the Shannan area of the eastern section of the Gangdese belt.Intrusion-related skarn copper mineralization belongs to high K and calc-alkaline rock series,located in the late collision magmatic arc and formed between 20 to 30Ma.Copper mineralization occurs at the exocontact zone of the lower Cretaceous Bima Formation carbonate and other calcareous-bearing sedimentary rocks with intrusions.At p... |
