摘要
大金山矿区位于大绀山弧形断裂带的中心,岩浆活动强烈,构造复杂。钨锡矿体沿主干断裂及旁侧的构造裂隙带近平行产出,主要矿化类型为石英脉型、构造破碎带-石英脉复合型和蚀变岩体型。根据最新矿产勘查成果,预计整个矿区WO3+Sn资源量大于8万吨,而且矿区大部分位于侵蚀基准面以上,易采易选,可成为广东一个新的大型钨矿产资源基地。
Dajinshan W-Sn deposit is located in the center of Daganshan arcuate fault zone with strong magmatie activity and complex structures. W-Sn ore-bodies are mainly occurred in main fault and flanking tectonic fissures with nearly parallel output, the main mineralization types are quartz-vein type, tectonic crushed zone-quartz vein complex type and alteration rock type. According to the latest mineral exploration results, it is expected that the entire mining area of W03 ＋ Sn resources greater than 80,000 tons, and the mine located above the base level of erosion, easy to adopt and election, could become a new large-scale tungsten mineral resource base in Guangdong province.
