摘要: 东坑金矿产于震旦系云开群中亚群,北东向吴川-四会大断裂是区内的重要控矿构造,大田顶弧形构造控制了矿床、矿点的分布,北西向韧性剪切带使金矿脉群定位;岩浆岩为成矿提供硫源外,还提供了热源和部分金质;金矿赋存于近接触带的绿片岩中,接触带为矿脉群的聚集、充填提供了空间。

Abstract: The Dongkeng gold deposit is located in the silicified quartz vein belts of the green schist belts in the middle subgroup of the Sinian Yunkai Group, and constrained by the NW-trending ductile shear zones. The sulfur, heat and gold in the gold deposit are derived mainly from the magmatic rocks. The contact zones of the gold deposit are believed to be favourable sites for the accumulation and filling of the ore vein groups. The ore controls include stratigraphy, tectonics and structures, magmatic rocks, lithologic associations and migmatitic contact zones.
