陕西双王金矿床中自然金属与金属互化物
首发时间:2017-05-04
摘要:在研究陕西双王金矿床物质组分的过程中, 通过对矿物的反光显微镜下观察与电子探针分析, 发现了自然金、自然铋的金属矿物以及黑铋金矿的金属互化物。这些自然金属矿物与金属互化物在卡林型、类卡林型金矿床中均较罕见产出, 其生成条件独特, 是在一种缺氧、低硫的较强还原环境中形成的,且反映了成矿作用与岩浆活动有密切联系。

Discovery of native metallic mineral and polymetallic compound in the Shuangwang gold deposit, Shanxi Provinces
Abstract:Examination of ores by optical microscope and EPMA from the Shuangwang gold deposit, Shanxi Province, has revealed native gold, native bismuth, and maldonite. It is rarely previously reported in the Carlin type and Carlin-like type gold deposit. These rare minerals formed in a strongly reducing environment with absent oxygen and low sulfur activities, showing close relation with magmatic activities.
