中文摘要:蛇屋山金矿是我国第一个人大型红土型金矿床。它具有规模大、品位低、易采、易选、经济效益好等特点,是黄金矿业中建设大型露采堆浸场的理想基地。这个矿床的成矿物质来自奥陶系碳酸盐岩硅化破碎带,成矿活动以第四纪化学风化作用为主。在中更新世热带雨林条件下,在岩石的红土化过程中,金从原岩中析出,与风化产生的铁质水溶液一起,沿着红土裂隙向下渗透,停积于地下潜水面,形成似层状矿体。
Abstract:Located in the hilly land of Jiayu County, Hubei Province, south of the Yangtze River, the Shewushan gold deposit is the first large-size lateritic gold deposit discovered in China, characterized by large dimensions, low grade, and readiness for mining and ore dressing. The metallogenic materials came from the silicified shatter zone of Ordovician carbonate rocks, and the ore-forming process was related to the Middle Pleistocene strong chemical weathering, during which gold was mobilized, transported and concentrated. The ore deposit is correlatable genetically with the Boddington lateritic gold deposit in western Australia. As for its relationship with the gossan gold deposits in middle and lower reaches of the Yangtze River, they were formed by different ore-bearing protoliths in the same metallogenic environment, belonging to two genetically similar industrial types in the same metallogenic series.
