1地质概况黄沙坪矿床位于湖南省桂阳县境内,是南岭成矿带乃至华南地区的一个重要的矽卡岩型钨钼铜铅锌多金属矿床,具有矿化范围集中、矿化分带明显等特点;并且传统上所认为的分属2套不同成矿专属性的中高温钨锡多金属和中低温铅锌多金属在矿区范围内大量产出,引起学者广泛关注。前人研究工作表明矿区的花岗质岩体为
1 Geological Survey Huangshaping deposit is located in Guiyang County, Hunan Province. It is an important skarn-type W-Cu-Cu-Cu-Pb-Zn polymetallic deposit in the Nanling metallogenic belt and even in southern China. Obvious and so on. And it is traditionally considered that there are two sets of medium-high temperature tungsten-tin-polymetallic and low-temperature lead-zinc polymetallics belonging to two different metallogenic specialties, which have been widely produced in the mining area. Previous research shows that the granite rock mass is
