The Zhuoma Cu-Pb-Zn ore body is in occurrence of big vein. The metallogenetic mother rock is the Indosinian composite rock body of quartz diorite porphyrite and quartz monzonite porphyry intruding into Tumugou Formation. The rock body has the alteration of ring plane “porphyry type” outwards from center. The metallogenesis is related with the silicification—sericitization. There is the metallogenetic series of porphyry Mo deposit in deep→skarn Cu deposit in middle part→veinform Cu-Pb-Zn deposit in the margin. The ore body discovered now is only the big veined ore body of middle-upper zonation of porphyry ore deposit. There is the prospecting potentiality of porphyry—skarn Co (Mo) ore body in the deep.
