摘要
阿根他拉矿床的控矿层位为二叠系黄岗梁组,矿床由侵入的花岗斑岩、沉积的碳酸盐岩及层间断裂构造破碎带共同控制,围岩蚀变有明显的分带现象,矽卡岩化近岩体处蚀变最强,赋矿岩石为矽卡岩、矽卡岩化大理岩。通过分析研究矿床的地质特征、成矿规律及控矿因素,提高对矿床的控制程度,确定了矿床成因,并指出了找矿标志。
The ore - bearing layer of Agentala Deposit is at Huanggangliang group of Permian , the deposit are col- lectively controlled by invading porphyry granite, sedimentary carbonate and fracture zone of interformational faulted structures , the wall - rock alteration has obvious zoning phenomenon, the highest skarnization alteration is near the rockbody, the host rocks are skarn and skarnization marble. Through analyzing geology characteristics, metallogen- ic regularity and ore - controlling factors of the ore deposit , the degree of controlling the ore deposits is improved, the genesis of deposit is determined, and the prospecting marks are points out .
