花岗岩型铀矿中,绿泥石化作为热液蚀变的重要类型之一,其种类多样,据此可以推断其形成环境。笔者在岩石薄片观察的基础上,通过对绿泥石进行电子探针成分分析,认为桃山大布铀矿床的绿泥石主要为铁绿泥石、蠕绿泥石,其形成于中低温酸性热液作用环境。

As one of the main hydrothermal alteration types in granite type uranium deposits,chlorite has several kinds which can be used to deduce its forming environment.In this paper,microscope and eG lectron probe micro analyzer (EPMA)were employed to study the chemical composition.The chlorite was believed mainly to be daphnite,ripidolite which are formed in the acid hydrothermal process of low moderate temperature.
