摘要
经显微镜及电子探针分析证实,广西珊瑚钨锡矿床中有深红银矿、硫银锡矿、银黝铜矿、块硫铋银矿、硫银铋矿和脆银矿六种银矿物。它们主要赋存于第Ⅲ矿化阶段的硫化物如闪锌矿、黄铜矿、黝锡矿中,形成于中温(227～277℃)、弱碱性(pH=7.6±)的岩浆热液环境。
According to data on microscope and electronprobing analyses it is con-firmed that there occur six kinds of silver minerals: pyrargyrite, canfiel-dite, freibergite, pavonite, matildite and stephanite in the Shanhu tungsten-tin ore deposit, Guangxi. They mainly exist in the sulfides, such as spha-lerite, chalcopyrite and stannite in the third stage of mineralization andare formed in the environment of mesothermal (227～277℃) weak-alkaline(pH=7.6±) magmatic hydrothermal solutions.
