中文摘要: 通过对紫金山东南矿段铜钼(金)矿床地质矿化特征分析,指出铜钼矿化带主要赋存于花岗闪长斑岩的内外接触带,处于似斑状花岗闪长斑岩的上部,金矿化带赋存在表生氧化带的英安玢岩、隐爆角砾岩中。经过对矿石的组构特征、矿物生成顺序等特征分析,将矿床的成矿演化过程分为斑岩热液期、高硫化浅成低温热液期、表生氧化期3个主要矿化期次,进一步将斑岩热液期分为黑云母-钾长石化阶段、石英-绢云母化阶段、碳酸盐化阶段三个阶段;高硫化浅成低温热液期分为地开石化阶段、明矾石化阶段、硅化阶段三个阶段。为进一步研究矿床成因提供依据。
Abstract:By the analysis of Geological characteristics of mineralization of the Zijinshan southeast ore block Cu-Mo deposit ,pointed out that the copper-molybdenum mineralization is mainly hosted by granodiorite porphyry inside and outside the contact zone ,in porphyritic granodiorite porphyry upper, Gold mineralization is hosted in dacite porphyry , breccia of supergene oxidation zone . By the analysis of fabric characteristics of the ore , mineral build order, the mineralization evolution of deposit is divided into three metallogenic periods, respectively, porphyry hydrothermal period, high sulfidation epithermal period and supergene oxidation period. Further the porphyry hydrothermal period is divided into three stages, respectively, biotite- K-feldspar stage, quartz- sericite stage, carbonate stage. The high sulfidation shallow epithermal period is divided into three stages, respectively, dickite petrochemical stage, alum petrochemical stage, silicification stage. To provide a basis for further study of genesis .(修改所有英文部分,保证专业名词和语法结构的准确性)
