摘　　要：白干湖钨锡矿床赋存在古元古界金水口群变质岩系中,矿体受北东向白干湖断裂带控制,加里东期酸性侵入岩与矿床关系密切.区内是钨元素地球化学高背景区,在各类地质体钨元素富集系数为9.57～25.30.目前共发现17条矿体,矿石类型为夕卡岩型白钨矿和石英脉型黑钨矿.矿床类型为沉积变质岩浆再造型钨锡矿床.The Baiganhu W Sn deposit,occurring in the metamorphic rock series of Paleoproterozoic Jinshuikou Group,is closely related to the Caledonian acidic intrusive rocks.The studied area is with a high geochemical background of W element.The enrichment coefficients of W range from 9.57 to 25.30 in various geologic bodies.Total 17 ore bodies have been discovered with scheelite ore of skarn type and wolframite ore of quartz vein type.The deposit belongs to the stratabound hydrothermal superimposed type of W Sn deposit.
