福建邵武金坑铜金矿地质特征及找矿前景分析

On the Geological Characteristics and Ore-finding Perspective of the Jinkeng copper and gold deposit in Shaowu City,Fujian Province

邵武金坑铜金矿体产于震旦纪西溪组、寒武纪林田组层间构造破碎带,矿体呈似层状、透镜状,受北北东向金坑断裂和坑口断裂构造控制。成矿物质来自含矿地层及后期的岩浆热液,认为矿床为破碎带蚀变岩型铜金矿床。

Jinkeng copper and gold deposit exist in the tectoinc fracture zone beteen Sinian Lam Tin West Brook group and the Cambrian formation. The orebodys acts like a veiny and lenticular occurrence, which is controlloed by the faulted structures with the NNE Jinkeng trend and Kengkou trend. Ore-forming materials come from the ore-bearing formation and the late magmatie hydrothermal. It is considered that the deposit belongs to the fracture zone altered rock type gold-copper.
