| 摘 要： | 木瓜园斑岩型钨矿位于洞庭湖拗陷区与雪峰隆起区结合处,处于安化-浏阳东西向构造带钨、锑、金矿带中段。钨矿体呈似层状产于三仙坝花岗斑岩体中,该岩体受北西西向F2断裂控制。钨矿石类型为细脉浸染状花岗斑岩型,硅化和硫化物化与成矿关系密切。成矿流体主要来源于三仙坝花岗斑岩体;成矿物质主要为壳幔混合来源。花岗斑岩中的石英细脉、粗大的石英斑晶颗粒、硅化都为矿床的找矿标志。三仙坝钨矿体向北西侧伏方向、北西西向F2断裂及两侧多斑花岗斑岩都具有较好的找矿潜力。

| Abstract: | Muguayuan porphyry tungsten deposit locates at the juncture of Dongting lake downwarping region and Xuefeng upwelling area, in the middle of Anhua-Liuyang East-West structural belt, which is a W, Sb, Au ore belt. The tungsten ore body is strati.ed in Sanxianba granite porphyry body, which is controlled by NWW trending fault F2. The type of tungsten ore is vein-disseminated granite porphyry, and the silici.cation and sul.de are closely related to tungsten mineralization. The ore-forming .uid mainly comes from sanxianba granitic porphyry. The ore-forming materials are mainly derived from crust-mantle mixture. The quartz veins in granite porphyry, coarse grains of quartz porphyry and silici.cation are prospecting marks. The northwest direction of Sanxianba tungsten ore body, the NWW trending fault F2 and the porphyry granite porphyry in the two .anks of fault F2 have good prospecting potential. |
