含汞金矿已在许多国家发现,如哥伦比亚和美国有含 Au38.39%、Hg37.4%、Ag5% 的汞金矿物——金汞膏;印度有含 Au 24.74%、Ag 61.51%、Hg14.47%的汞金矿物。苏联对自然金中的汞含量作过较系统的研究,发现很多自然金都含有一定量的汞(汞含量为 0.1—0.5%或稍高),并在一些地区的自然金中也有富汞相的存在。我国某含铂超基性岩体中段的蚀变辉长岩中和某含金中基性火山杂岩系上段的黑云母变粒岩中,也先后发现了α、β和γ相的金、汞、银的天然互化物,但是由于矿物的粒度细小,而且数量很少,这些矿物仅在人工重砂和砂矿中见到。因此,矿物在矿石中的产出情况未作报道。笔者在研究川西呷村多金属矿床中 Au、Ag、Hg 的赋存状态时,除发现自然金外,还发现了富汞金矿物,并对这两个矿物的产出、物理光学特性以及化学成分进行了较系统地研究,认为呷村富汞金矿与目前已知的金汞矿物有某些不同之处。现将这两个金矿物的特性、产出情况和迁移、富集作用加以讨论,对丰富矿物学的内容,深入探讨呷村多金属矿床的成因及对该矿床的综合利用具有十分重要意义。
Mercury-bearing gold deposits have been found in many countries, such as mercury and mercury amalgam containing Au38.39%, Hg37.4% and Ag5% in Colombia and the United States; Au-mercury amalgam in India with Au of 24.74%, Ag of 61.51%, Hg14 .47% of mercury gold minerals. The Soviet Union made a systematic study on the mercury content of natural gold and found that many natural gold contains a certain amount of mercury (mercury content of 0.1-0.5% or slightly higher), and mercury-rich phase in natural gold in some areas The presence. In the alteration gabbro in the mid-section of a certain platinum-bearing ultramafic rock mass and the biotite granulite in the upper section of a gold-bearing medium-basic volcanic complex, gold, mercury, However, due to the small size and small number of minerals, these minerals are only found in artificial heavy sands and sands. Therefore, the output of minerals in ores has not been reported. In the study of the occurrence of Au, Ag and Hg in Quncun polymetallic deposit in western Sichuan, besides the discovery of natural gold, the authors also discovered the mercury-rich gold minerals, and found the output, physical optical properties and chemical The composition of a more systematic study, that Kojima mercury-rich gold and currently known gold and mercury minerals have some differences. Now, the characteristics of these two gold minerals, their output and the role of migration and enrichment are discussed. It is of great significance to enrich the contents of mineralogy, discuss the genesis of the Quncun polymetallic deposit and its comprehensive utilization.
