内蒙古额仁陶勒盖大型独立银矿床产于以安山岩-玄武岩为主的火山一次火山岩中,矿体倾断裂构造产出,主要矿体分布于南北长近10km,东西宽约15km的范围内,除银外,伴生的铅、锌、锰等均不具工业价值。该矿床已发现银的独立矿物20余种,主要与黄铁矿、菱锰矿及少量方铝矿、闪锌矿共生。地质特征显示出了矿床相对于围岩的后成特点,地球化学证据表明该矿床的形成是以火成宕(火山-次火山岩)为矿源岩的后成改造型银矿床。
The Renren Tolgoi large-scale independent silver deposit in Inner Mongolia was produced in a volcanic volcanic rock mainly consisting of andesite and basalt. The ore body is produced by the tectonic decollement. The main orebodies are distributed in the range of nearly 10km from north to south and 15km from east to west, In addition to silver, associated lead, zinc, manganese, etc. are not of industrial value. The deposit has found more than 20 kinds of silver independent minerals, mainly with pyrite, rhodochrosite and a small amount of siderite, sphalerite symbiosis. Geological features show the post-formation characteristics of the deposit relative to the surrounding rock. Geochemical evidence indicates that the deposit was formed as a post-retrogressive silver deposit with source rocks of volcanic-secondary volcanic rocks.
