| Abstract: | The Mingze porphyry molybdenum deposit in Shannan,Tibet,is mainly composed of concealed massive molybdenum orebodies,which are covered by thick Paleogene Luobusa molasse.It lies in the suture zone between the Gangdise-Nyainqentanglha plate and the Himalayan plate.The deposit is hosted in K-feldspar granite and monzonitic granite-porphyry.From the top to the bottom of the orebody,alteration varies from propylitic alteration,argillization,phyllite-like alteration,pyritization to silicification and potassic al... |
