滇黔桂“金三角”是我国卡林型金矿的主要的集中产出区域,具有金矿点多、分布面广,且含矿层位岩性各具特色,矿石类型复杂多样、矿产资源储量巨大等特点,素有“中国金州”之称。近年来,在台地相区受构造蚀变体控制的层控型金矿找矿取得了重大突破,其中仅赋存于构造蚀变体(一套为强硅化灰岩、灰质角砾岩、硅化粘土岩的岩性组合)中的水银洞金矿Ⅰa金矿体储量就大于25t(单矿体达大型规模)[1-2]。因此普遍认为这套构造蚀变体为金矿的重要含矿岩系,故而深入研究该地区构造蚀
Yunnan, Guizhou and Guangxi “Golden Triangle ” is the main concentrated output area of Carlin-type gold deposit in our country. It has many gold deposits and has a wide distribution. The lithology of the ore-bearing layers has its own characteristics. The ore types are complex and diverse. Mineral resources Large reserves and other characteristics, known as “China Jinzhou ” said. In recent years, significant breakthroughs have been made in the prospecting of stratiform controlled gold deposits controlled by tectonic alteration in the platform facies, of which only the tectonic alterations (a set of strong silicified limestone, gray breccia, silicification The lithologic combination of clay rocks), the reservoir of the Ia gold deposit is over 25t (single ore mass up to a large scale) [1-2]. Therefore, it is generally accepted that this structural alteration is an important ore-bearing rock series in gold mines. Therefore,
