| 摘 要： | 铜厂沟金矿床围岩蚀变强烈，并受构造脉动的控制，蚀变具不规则环形分带；蚀变作用划分为硅化－绿泥石化、硅化－碳酸盐化、黄铁矿化和硅化－黄铁矿化等四阶段，金矿化发生在黄铁矿化阶段。根据围岩蚀变特征，在已知矿体的下部，可以寻找构造－蚀变岩型金矿体。

| Abstract: | The country rock alteration at Tongchanggou Gold Deposit is well developed and the deposit is controlled by tectonic pulse. The alteration shows irregular ring shape zonations which are divided into four stages i.e. silicification chloritization, sililcification carbonization, pyritization and silicification pyritization. The Gold mineralization occurs in pyritization stage According to characters of country rock alterations, tectonic altered rock type Gold deposit can be explored under the known orebodies. |
