辽南地区金矿与侵入岩的关系

The relationship between gold deposits and intrusive rocks in the Southern Liaoning Province

辽南地区是我国重要的金矿集中区之一。该区具有良好的金矿成矿地质条件,金矿类型较多,分布范围较广,具有很好的找矿前景。据目前的资料表明,该区金矿的成矿热液及矿质主要来自岩浆,岩浆中含金一是直接来自地幔,二是重熔岩浆继承了太古界基底的高金丰度,所以,该区的岩浆活动是金矿成矿的关键因素。在此基础上,具备了地层及构造上的有利条件,就形成了该区各种类型的金矿床。

The Southern Liaoning Province is an important gold mineralization area with nice conditions for gold mineralization, e. g. , many types of gold deposits, large area distribution, good potential for exploration. According to the present data, the ore - forming solution and elements are mainly from the magma in this area, and the gold in magma is not only from the mantle directly but also from the Archean basement with high gold abundance. Therefore, the magmatic activity is key for gold mineralization in this area, as well as favorable strata and structure.
