Wangshe deposit is located in Guangxi province. It is a Cu-W deposit associated with porphyry type copper and quartz vein-type tungsten related to Mesozoic granites. The molybdenite apparent Re-Os age is 94.9～96.3 Ma with an isochron age of 93.8±4.6Ma (n=6). Kunlunguan batholith is mainly composed of biotite granite cut by later granitic porphyry dykes. The SiO2 of the former is 68.6%～72.1%, and that of the latter is 73.8%; The Al2O3 of the former is 14.16%～14.75%, and that of the latter is 14.07%; The total alkaline of the former is 6.78%～8.15%, and that of the latter is 8.1%. We indicate that the geodynamic evolution of Late Yanshanian mineralization in this region is lower crustal delamination and lithospheric thinning.
