摘要
在黔东南地区,蚀变岩型金矿是一种研究程度较低的新类型金矿。本文采用化学分析、物相分析、电子探针扫描、X射线面扫描分析等综合分析技术对金矿进行了金的赋存状态研究。研究表明金主要以独立矿物相存在,金的载体矿物主要为毒砂、黄铁矿。金矿物主要是含银自然金,平均成色约884.45。金的嵌布类型有粒间金、包裹金、裂隙金三种。
In the southeast Guizhou, altered gold mine is a new type which was studied in a low degree. In this paper, with chemical analyses, phase analyses, Electron -probe scanning, X -ray surface scanning and some other methods, it studied the modes of gold occurrence for the gold mine. The study showed that the gold existed mainly as single mined phase, the carrier mainly are arsenical iron, iron pyrites. Gold mineral mainly is native gold which contain silver, the average fineness is about 884. 45. Gold is embodied as intercrystal, inclusion and fissure -filling form.
