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 alteration. The age of intrusive rock is Paleogene Oligocene, and the Re-Os isotope age of molybdenite ore is 30 Ma. The discovery of the Mingze deposit provides helpful evidence for prospecting similar porphyry molybdenum (copper) deposit along the southern margin of the Gangdise metallogenic belt.
