【摘要】 云南锡矿床可别为亲石和亲硫两大系列,亲石系列包括含锡稀有金属伟晶岩型、锡石—石英—电气石—云英岩型锡矿床;亲硫系列包括含锡矽卡岩型、锡石—碳酸盐—硫化物型锡矿床 研究了两大系列锡矿床在云南的分布,以红河断裂为界,云南西部主要分布为亲石系列锡矿床,以陆壳碰撞型的原地半原地交代—重熔花岗岩为主。云南东部主要为亲硫系列锡矿床,以壳下重熔花岗岩为主,具异地侵位特征。 综合锡矿床的地质特征。建立了两大系列锡矿床的成矿模式。更多还原

【Abstract】 Tin deposits in the Yunnan province can be broadly classified into two series: lithophile and sulphophile . The lithophile series includes tin deposits of stanniferous rare metal pegmatites and cassiterite-tourmaline-quartz-greisen type. The sulphophile series includes tin deposits of stanniferous skarns and cassiterite-carbonate-sulfide type.The study on the distribution of these two series of tin deposits in the Yunnan province shows that they are distributed in two different areas, separated by the Honghe (Red River) Fault. Lithophile series tin deposits are extensively developed in western Yunnan. The associated granites are mainly autochthonous to semi-autochthonous of metasomatic-to remelting type and related to continent-continent collisions. Tin deposits of the sulphophile series are predominantly distributed in eastern Yunnan. The granites are predominantly of subcrustal remelting type with allochthonous emplacement characteristics.In summary of the characters of the deposits ,a metallogenic model of two series tin deposits has been set up.更多还原
