| 摘 要： | 高庄金矿是一个脆-韧性剪切带型中温热液金矿床,矿化蚀变以强石英-绢云母化为特征,剪切带的控矿作用表现为:剪切带控制石英脉带(群);剪切带内的一系列张裂隙控制含金石英脉;变形作用最强烈的碎裂地段控制工业矿体的三级构造控矿体系。含金石英脉在剪切带中呈“百叶窗”式的空间分布。成矿作用分为表生成矿期及内生成矿期,内生成矿期又可分为少硫化物石英脉阶段、磁黄铁矿-金-石英脉阶段、金-黄铁矿-石英脉阶段和石英-碳酸盐岩4个成矿阶段,其中第2、3两个阶段为主要成矿阶段。表生期的局部差异条带状风化,是由于磁黄铁矿与黄铁矿的抗氧化强度不同造成的。

| Abstract: | Gaozhuang Gold Deposit is a shear zone type epithermal deposit,the main character of mineralization and alteration is intense quartz-sericite,the shear zone controls orebodies as follows:shear zone controls quartz veins,a series of ringent crannys control gold-quartz vein,(grades structure system controling orebodies is controled by the smash segments which suffered the most strong distortion.Gold-quartz vein distribut in shear zone with“jalousie”mode.The metallogenesis is divided into two stages-endogenetic and exogenous formation,the former comprises four stages:sulfuret-short quartz-vein stage,magnetic pyrite-gold-quartz-vein stage,gold-pyrite-quartz-vein stage and quartz-carbonate one,and the second and the third are the main ore-metallogenic stages.Due to magnetic pyrite and pyrite have different capable to resist oxidation,the zonal weathering in exogenous stage has partial different from others. |
