安徽省池州市查册桥——小何一带辉钼矿Re-Os年龄及地质意义

Re Os age and geological significance of Molybdenite in chaciqiao Xiaohe area,Chizhou City,Anhui Province

研究区位于扬子陆块北缘,大别造山带和江南造山带的间夹部位。本次通过对研究区内的主要金多金属矿中辉钼矿Re-Os同位素测定以及与邻区典型矿床对比,认为柴山金多金属矿、牌楼金多金属矿的成矿物质主要来源于壳幔混合源,且与马头铜钼矿等斑岩型矿床为同一构造-岩浆热事件的产物,暗示这两个矿床均具寻找斑岩型铜金矿的找矿潜力。

The study area is located in the northern margin of the Yangtze block,between the Dabie orogenic belt and the Jiangnan orogenic belt.Through the Re Os isotopic determination of Molybdenite in the main gold polymetallic deposits in the study area and the comparison with the typical deposits in the adjacent area,it is believed that the ore-forming materials of Chaishan gold polymetallic ore and pailou gold polymetallic ore mainly come from the mixed source of crust and mantle,and they are the products of the same tectono magmatic thermal event as those of Matou copper molybdenum ore and other porphyry deposits,suggesting that the two deposits are both porphyry copper gold deposits The prospecting potential of the mine.
