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 。
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,Ⅲ 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.
