GEOLOGICAL CHARACTERISTICS AND PROSPECTING INDICATORS OF WOMAGOU GOLD-COPPER DEPOSIT IN QINGHAI PROVINCE

The Womagou gold-copper deposit, located in the Ela Mountain area of eastern Kunlun metallogenic belt, is occurred in the Early-Middle Triassic Longwuhe Formation as stratoid and lentoid structures, strictly controlled by the E-W-and NE-trending faults. Currently, two gold and ten copper ore/mineralized bodies were found, with deposits dominated by the epi-mesothermal magmatic and structural altered rock types. Based on the analysis of geological, geophysical and geochemical characteristics, it is thought that Ag is well correlated with Au and Cu, and has a great metallogenic potential, thus more attention should be paid in future prospecting. Further analysis shows that the sand slate of Longwuhe Formation serves as the main source bed in the area. The secondary interlayer fissures derived from the E-W fault provide favorable positions for the enrichment of orebodies. The soil anomalies of Au and Cu, banded and beaded low-gentle magnetic anomalies and IP anomalies with low resistance and high polarization are important prospecting indicators for gold-copper deposits.
