| [摘要]高坳背钨钼矿是近年发现的、具大型远景规模的蚀变岩体型钨钼矿，区内地层主要为震旦系的硅质岩及寒武系的浅变质岩，褶皱、断裂构造不发育，矿区东部大面积出露晚三叠世二长花岗岩。围岩蚀变主要有角岩化、钠长石化、云英岩化、萤石化、电气石化、绿泥石化、绢云母化，其中钠长石化、云英岩化与矿化关系密切。钨钼矿产于花岗岩北西西向的蚀变带中，矿体规模大，延伸稳定，矿化连续，品位富。该矿床的发现不仅为在南岭成矿带湘赣交界一带的蚀变岩体型钨钼矿的找矿突破具有重要的指导意义，而且对研究区内钨钼矿的成因及与花岗岩的关系等指出了新的方向。 |

| Abstract: The Gao’aobei tungsten-molybdenum deposit is a newly-discovered large-scale altered rock type deposit. The outcropped strata are mainly Sinian silicastone and Cambrian metamorphic rocks. Folds and faults are few in this area . The late Triassic monzonitic granites largely occurred in the eastern part of the ore district. The wall rock alterations are dominated by hornstonization, albitization, greisenization, fluoritization, tourmalinization, chloritization and sericitization, of which the albitization and greisenization are closely associated with the mineralization. The tungsten-molybdenum ore bodies are hosted in the NWW direction alteration belts. They are of large-scale, extend stably, have continuous mineralization and are of high-grade. The discovery of the Gao’aobei deposit is not only a significant guidance to ore-prospecting breakthrough of altered rock type W-Mo deposits around the boundary between Hunan Province and Jiangxi Province in the Nanling metallogenic belt, but also a new direction to study the genesis of tungsten-molybdenum deposits related to granites. |
