独石岭钨-铜多金属矿床位于南岭西段苗儿山-越城岭岩体北东部,为一个大型蚀变岩型+矽卡岩型钨铜多金属矿床。通过对坑道内与矿有关的花岗岩中锆石LA-ICP-MS定年结果表明,与矿有关的花岗岩有两期:加里东期和印支期。加里东期花岗岩有两种类型:中粒似斑状黑云母花岗岩和中细粒黑云母花岗岩,两类花岗岩在时空上与矿体关系密切,应属于独石岭钨-铜矿成矿母岩。对两类花岗岩进行的锆石LA-ICP-MS U-Pb定年结果表明,中粒似斑状黑云母花岗
The monolithic tungsten-copper polymetallic deposit is located in the northeast of the Mianershan-Yuechengling pluton in the west section of Nanling, and is a large-scale altered rock type + skarn tungsten-copper polymetallic deposit. The results of LA-ICP-MS dating of zircons in the granite associated with ore in the tunnel show that there are two types of ore-related granites: the Caledonian and Indosinian. There are two types of Caledonian granites: medium granuliform-like biotite granites and medium-fine biotite granites. Both types of granites are closely related to ore bodies in time and space and should belong to the monolithic tungsten-copper ore-forming parent rock. The zircon LA-ICP-MS U-Pb dating of the two types of granites shows that the medium-sized granodioritic biotite granite
