Located east to Gangdisi tectonic metallogenic belt, Tangbula porphyry-type Mo （Cu） deposit boasts advantageous metallogenic conditions. The article analyzed the geological background of mineralization, the time of digenesis and mineralization, the source of ore-forming materials, the process of mineralization, the state of orebodies occurrence, and finally established a metallogenic model. Results have shown that the digenesis and mineralization of Gangdisi porphyry-type copper deposit occurred intensively in the Himalayan period, the formation is related to the northward subduction of Tethyan oceanic crust into the bottom of the Lhasa terrane. The ore-bearing rock are mainly intrusive rocks of intermediate acid calc-alkaline rock series with characteristics of adakitic rock. The mineralization pattern is of practical significance to regional mineralization forecast and metallogenic model establishment.
