摘　　要：牛塘界钨矿床是南岭成矿带西段重要的大型钨矿床。钨矿化主要产于寒武系清溪组特定层位中,矿体总体走向北西,呈层状、似层状产出;矿石类型主要以矽卡岩型为主,石英脉型次之;矿石主要金属矿物为白钨矿、黄铁矿、方铅矿等。在前期以往地质工作及专家学者科研论述的基础上,总结矿床地质特征,建立了矿床的成矿模式,认为该矿床为受地层层位(岩性)、构造及岩浆岩控制的矽卡岩型矿床,为在桂北牛塘界一带开展深边部找矿工作寻找该类型的矿床提供参考。Niutangjie tungsten deposit is an important large scale tungsten deposit in the western segment of Nanling metallogenic belt.The tungsten mineralization mainly occurs in the specific strata of Cambrian Qingxi Formation.The ore beds generally strike in NW and appear stratified or similar to stratified occurrence.The ore type is mainly skarn type,followed by quartz vein type.The main metallic minerals of the ore are scheelite,pyrite,galena,etc.Based on the previous geological works and researches we summarize the geological characteristics and establish the metallogenic model of this deposit.It is considered that the deposit is a skarn type deposit controlled by stratigraphic lithology,structure and magmatic rock.There can provide a reference for carrying out ore prospecting work in the deep margin of Niutangjie area in North Guangxi to find this type of deposit.
