摘要
桂东北钨矿位于南岭成矿带的西段,钨多金属矿集中分布于越城岭—苗儿山岩体群、海洋山—都庞岭岩体群和花山—姑婆山岩体群,与岩浆岩和构造关系密切,钨与锡、钼、铌钽等多金属共生和伴生,具有岩浆热液型、矽卡岩型、长英质岩体型等矿床类型,成矿时代为加里东期、印支期、燕山期。以斑岩-矽卡岩钨多金属矿为找矿主线,形成“多位一体”钨矿找矿思路,提出苗儿山—越城岭复式岩体与围岩的接触带中矽卡岩型白钨矿找矿靶区和珊瑚钨锡矿深部、西部找矿靶区,对比钨矿成矿规律,突破找矿新类型,开展深部找矿勘查,对区内找矿突破具有指导意义。
Northeast Guangxi tungsten deposits are located in the west section of the Nanling metallogenic belt,and tungsten polymetallic deposits are concentrated in Yuechengling-Miaoershan rock mass group,Haiyangshan-Dupangling rock mass group and Huashan-Guposhan rock mass group.They are closely related to magmatic rocks and structures.Tungsten is coexisting and associated with polymetallic metals tin,molybdenum,niobium and tantalum.There are magmatic hydrothermal type,skarn type,felsic rock type and other deposit types.The metallogenic ages are Caledonian Period,Indosinian Period and Yanshan Period.Taking the porphyry-skarn tungsten polymetallic deposit as the main prospecting direction,the"multi-locationone-body"tungsten ore prospecting idea is formed,and the prospecting target area of the skarn type scheelite deposit in the contact zone between the Miaoershan-Yuechengling complex pluton and the surrounding rock is proposed.The deep and western prospecting target area of the Shanhu tungsten-tin deposit is also proposed.Comparing the metallogenic regularity of tungsten deposit,breaking new prospecting types,and carrying out deep prospecting exploration have a guiding significance for the breakthrough of prospecting work in the area.
