摘要
本文在阐述浙西中生代产铀火山岩区隐爆岩产出地质背景的基础上,根据隐爆岩胶结物种类及结构构造特征等综合因素,将该区隐爆岩划分为4大类9个亚类。文章还讨论了它们的形成机理,强调了碎屑型及气热型爆裂角砾岩和爆裂岩类对铀矿的控制作用,并指出了隐爆岩型铀矿的找矿方向。
According to the formatinn geological setting of types of cementing material and texture feature of cryptoexplosion rock in mesozoic uranium-bearing volcanic area in west Jiang province,the cryptoexplosion can be classified into four groups and nine subgroups. Its formatinn mechanism is discussed. It is emphasised that the control of the explosion-split breccias and explosion-split rock of detrital type and hydrothemal type over uranium metallogenesis. The paper also points out the prospecting direction of uranium deposits of cryptoexplosion rock type.
