| Abstract: | Multi elements primary geochemical anomalies are well developed in the Qulong porphyry Cu Mo deposit. The anomalies of ore forming elements Cu and Mo(Ag) are characterized by high intensity and large size, and accord quite well with the mineralization. The anomalies of associated elements Au, Bi, Pb, As, Sb and Hg are mainly distributed on both sides of the ore anomalies, whereas the anomalies of B Co and Ni Mn Zn are spread around the ore anomalies. Na2O occurs as negative anomalies while K2O appears as positive anomalies in the ore district. Based on the above-mentioned association of elements, the horizontal zoning, and the Na2O poor and K2O rich ore forming environment, it is considered that the Qulong Cu-Mo deposit is a typical porphyry deposit subjected to strong denudation. |
