摘要
铁帽型金矿床是在多金属硫化物矿床的基础上,经过表生作用,矿体中的物质成分发生分解而形成的.由于各种金属的物化特性不同,有的溶解随水流失,有的在氧化带富集成矿,因而自上而下形成金、银、铜的次生富集矿体,构成明显的分带特征.
The gossan type gold deposits were derived from multimetallic sulphide deposits through supergenesis. Metallic material constiuents in ore bodies in these deposits were decomposed, and becauseof their different characteristics. some of them were dissolved in and gone away with the runningwater and others were concentrated in oxidation zone to form the ores. Thus a secondary enrichedorebody was formed with a distinct zoning of gold, silver and copper from its top to the bottom.
