云南广南地区老寨湾微细粒浸染型金矿床地质特征与成矿规律探究

Geological characteristics and metallogenic regularity of the fine disseminated gold deposits in the old bay, Yunnan, Guangnan

云南地区目前首个被查明并进行正式开发的较大型金矿,其位于云南东南方向的金三角地区,即老寨湾矿山。该矿山的成矿条件优越,为矿藏的开采带来了良好的预期,且被云南省定为首要调研勘探对象。本文通过对该地区的侵染型金矿的地质情况进行了认真阐述,对金矿形成规律及与对应的地质变化情况进行了分析,并对寻矿工作的关键提出了建议。

The first large scale gold deposit, which has been identified and developed in Yunnan area, is located in the southeast of Yunnan, which is located in the southeast of Golden Triangle. The metallogenic condition of the mine is superior, which brings good expectation for the exploitation of mineral resources, and is regarded as the primary exploration object in Yunnan province. In this paper, the geological conditions of the gold deposits in this area are expounded, and the regularity of gold deposits and the corresponding geological changes are analyzed.
