| 摘 要： | 本文采用矿相显微镜研究、金溶解性试验、化学分析、背散射电子面扫描、二次电子面扫描、晶体X射线衍射等手段对青海五龙沟金矿床矿石、矿物的含金性及金的赋存状态进行了研究。结果表明，多次叠加蚀变及黄铁绢英岩化毒砂伦金矿石含金较高，金主要以超显微状态存在于毒砂、含砷黄铁矿等金矿硫化物中，存在形式可能为小于10．0nm的非晶格金状态，矿石及矿物中典型元素组合为Au-As-Sb. |

| Abstract: | By means of mineragraphic microscope, gold solving test, chemical analysis, plane-scanning by back-emission electron, plane-scanning by secondary electron and X-ray diffraction, this paper studies the content and occurrence of gold in minerals and ores from the Wulonggou gold deposit, Qinghai Province. The conclusion is that the gold content of ore formed by poly-stage alteration, which consists of pyrite, sericite, quartz, and arsenopyrite, is high. Gold exists mainly in sulfides such as arsenopyrite and arsenomarcasite in the ultra-micro state. The gold may be of amorphous state, is less than 10×10-9 in size. The typical elements in the gold ore and its minerals are Au, As, Sb. All the above data are of great importance for determining exploration signs and guiding ore exploration of this gold deposit, and for drafting correct ore dressing and smelting project. This paper is also of great reference value for the same type of high-arsenic, fine-grained and disseminated gold ores. |
