广西有色金属成矿系列与成矿区带

根据不同类型和不同矿种的矿床在成因上的联系和时、空上的分布规律,可将广西有色金属矿床归为6个成矿系列,即热水沉积-叠生改造成矿系列、花岗岩成矿系列、热卤水成矿系列、基性-超基性岩成矿系列、地台型海相沉积成矿系列和表生成矿系列,其中热水沉积-叠生改造成矿系列是广西锡、铜、铅、锌、金、银、锑、汞等矿种最重要的成矿系列。按成矿系列的区域性分布特征及其与不同构造层的关系,笔者划分了9个主要成矿区带,即丹池锡-铜-铅-锌-银-锑-汞成矿带、桂北锡钨-铜-镍-铅-锌成矿带、桂东北锡-钨-铜-铅-锌金银成矿带、大明山钨-铜-金成矿带、大瑶山铜-铅-锌-金成矿带、云开大山铅-锌-钨-金成矿带、西大明山铜-铅-锌-银成矿带、桂西金-锑成矿带、靖西-平果铝成矿带。

Metallogenic series and metallogenic belt of nonferrous metals in Guangxi

Nonferrous metal deposits in Guangxi can be classified in to six ore forming series according to metallogenesis and space-time distributing laws of different types and different species of ore deposits. They are hot water deposition-diplogenetic transformation metallogenie series, granite metallogenie series, hot brine metallogenic series, basic rock-ultrabasic rock metallogenic series, platform type marine depositon metallogenic series, hypergene metallogenic series. The hot-water deposition-diplogenetic metallogenic series is the most important metallogenie series of Sn, Cu, Pb, Zn, Au, Ag, Sb, Hg in Guangxi. 9 Guangxi. metallogenie belts have been plotted out according to the regional distribution of metallogenic series and their relation with structural layer. They are Danehi Sn,Cu,Pb, Zn,Ag,Sb,Hg metallogenie belt, Guibei Sn-W- Cu-Ni-Pb-Zn metallogenie belt, Guidongbei Sn-W-Cu-Pb-Zn-Au-Ag metallogenie belt, Damingshan W,Cu, Au metallogenic belt, Dayaoshan Cu,Pb,Zn,Au metallogenic belt, Yunkaidashan Pb-Zn-Au-W metallogenic belt, Xidamingshan Cu-Pb-Zn-Ag metallogenic belt, Guixi Au-Sb metallogenic belt, Jingxi-Pingguo Al metallogenic belt.
