The Metallogenic Type and Ore-Prospecting Potential of Yuelong Copper Deposit
摘要
Abstract
According to the analysis of ore-forming geological environment, ore deposit geology feature,rock mass, and mineralization characteristic of Yuelong lead and copper deposit, we have realized that this deposit is located the south of the Hongliuhe-Niuquanzi-Xichangjing suture zone and belongs to the Early Paleozoic Passive continental margin. The ore-bearing strata are Dahuoluo Mountain Group of the Qingbaikouan System, its parent rock is granitic porphyry. The mineralization discovered mainly located in the contact zone between dolomite and granitic porphyry. On the basis of petrochemistry data, we hold that the granitic porphyry is the S-type granite, having the character of kaligranite. Comparing the Gongpoquan and Baishantang Porphyry copper deposit found in this area, we think that they are the same genetic type of ore deposit. In consideration of the shallow denudation of the granitic porphyry in Yuelong copper and lead deposit and there are more similar rock masses, the we think that finding more Porphyry copper deposits in this area is quite possible (including fine veins-disseminated in rock mass and metasomatism filling in contact zone and vein-type out of the rock mass) .关键词
