卡林型金矿成矿条件研究--以贵州拉旦-董万金矿床为例

Study on Mineralization Conditions of Carlin-Type Gold Deposit——Taking Ladan-Dongwan Gold Deposit in Guizhou as an Example

随着70年代后期我国发现卡林型金矿以来,到目前已发现200多处矿化点、矿点和矿床,探明了一批大型和中小型矿床,少数矿床的储量接近超大型矿床的规模。目前,微细浸染型金矿床已成为我国主要的热液金矿床类型之一,并日益显示出较大的找矿潜力、良好的成矿远景和重要的经济价值。结合在贵州拉旦-董万金矿床所开展的地质工作,并结合我国滇-黔-桂卡林型金矿化集中区的形成条件、分布规律及成矿作用特征等方面进行分析,进而对卡林型金矿床的成矿条件进行系统的总结。

With the discovery of Carlin type gold deposit in China in the late 70 s, more than 200 mineralization spots, mines and deposits have been found. A large number of large or small and medium deposits have been identified, and the reserves of a few of them are close to that of the superlarge deposit. At present, the microfine disseminated gold deposits have become one of the main types of hydrothermal gold deposits in China, and are increasingly showing great potential for prospecting, good metallogenic prospect and important economic value. According to the geological work carried out in the Ladan-Dongwan gold deposit in Guizhou Province, and analysis on the formation conditions, distribution rules and metallogenic characteristics of Yunnan-GuizhouGuangxi Carlin-type gold mineralization concentrated area, the metallogenic conditions of Carlin type gold deposit were systematically summarized.
