花岗岩类中锡、钨同铀的共生是一个世界范围的现象,但这个事实在过去没有被人们足够重视。最近,澳大利亚已经开始根据这个原理来区分有矿和无矿的花岗岩类。在澳大利亚,含Sn和W的花岗岩类有很多分析结果,但缺乏测定铀的资料。在有铀分析数据的地方,则不管含锡钨花岗岩的年龄、地理位置和性质,铀富集是一个共同的特征。 The symbiosis of tin and tungsten with uranium in granite is a worldwide phenomenon, but this fact has not been given enough attention in the past. Recently, Australia has begun to distinguish between ore-bearing and ore-free granite classes based on this principle. In Australia, there are many analyzes of the granitic classes that contain Sn and W, but lack the data to measure uranium. Where uranium was used for data analysis, uranium enrichment was a common feature regardless of the age, geography and nature of the tin-tungsten-bearing granite.
