夹皮沟金矿床区域地质及地球化学背景

Regional Geological and Geochemical Background of the Jiapigou Au Deposit

夹皮沟金矿位于吉林省烨甸县东部,是我国黄金生产重要矿山之一。自上世纪五十年代末开始至今,地质学者对夹皮沟金矿的地球化学找矿工作已取得了较好的成果,本文在多年来生产、科研实践资料基础上对夹皮沟金矿的区域地质及区域地球化学背景进行研究。研究结果表明,夹皮沟地区Au以自然金为主,夹皮沟金矿成矿属于中温成矿,成矿流体及含金石英脉成矿流体主要呈碱性,Au的含量从正常场→近矿围岩→蚀变带→含金石英脉依次增加一个数量级。

The Jiapigou Au mine lying in the east of Huadian, Jilin is one of important Au mines in China. Many results of study of geochemical prospecting have been obtained since 1950s. This paper sums up regional geological and geochemical background of the Jiapigou Au deposit on the basis of productive practice and science research for many years. Gold occurs as native gold. Ore fluids were alkaline. The Au deposit is a mesothermal deposit.
