| 摘 要： | 河南嵩县东湾金矿受构造蚀变带控制，矿体形态呈脉状或透镜状.矿石呈浸染状、细脉-浸染状、脉状-网脉状和蜂窝状等.围岩主要蚀变类型包括硅化、绢云母化、高岭石化、碳酸盐化、钾长石化、黄铁矿化.成矿阶段可分为4段：（1）硅化（黄铁矿）阶段；（2）石英-粗粒黄铁矿阶段；（3）石英-细粒黄铁矿阶段；（4）碳酸盐铅锌阶段.各阶段自然金矿物生成顺序是：自然金→银金矿→自然银→硫盐矿物.文中利用构造叠加晕原理，建立了河南嵩县东湾金矿构造叠加晕模式，并利用该模式对东湾金矿进行了成矿预测.

| Abstract: | The Dongwan gold deposit in Songxian, Henan Province is controlled by a structural alternation zone. The orebodies occur as veins or lenses, with ores in veinlets, disseminated, veins, stockworks and honeycomb-style. The ore minerals include natural gold, electrum and natural silver, with minor sulfates. The main alternations consist of silicification, sericitization, kaolinization, carbonation and pyritization. The mineralization is divided by four stages: silicification (pyritization) stage, quartz-coarse pyrite stage, quartz-fine pyrite stage and carbonate-galena-sphalerite stage. Based on the theory of structural overprinted geochemical halo, the model of structural overprinted geochemical halo for Dongwan gold deposit is constructed, by which blind orebodies are prospected successfully. |
