一般都赞同Sn-W矿床与来源于大陆地壳部分熔融的花岗岩或流纹岩有关,其构造背景或是在会聚型板块的边缘,或是在陆内裂谷带. 锡和钨几乎总是以锡石、以钨铁矿-钨锰矿固溶体系列所代表的黑钨矿以及以白钨矿的形式产出,而伴生的硫化物矿物共生组合有很大变化。黄铁矿-磁铁矿是比较常见的,黄铜 The Sn-W deposit is generally associated with granite or rhyolite that is partially melted from the continental crust, with tectonic setting either at the edge of convergent plates or in intracontinental rift zones. Tin and tungsten are almost always Cassiterite is produced as wolframite represented by the series of tungsten-iron-tungsten-manganese solid solutions and scheelite, while the accompanying sulfide mineral assemblages vary greatly. Pyrite - Magnetite is more common, brass
