本区铀、多金属矿床的形成与中生代晚期（Ｊ＿３－Ｋ＿１）火山活动关系十分密切。深部构造变异带和局部横向拉张部位是成矿的最佳环境。迭置在古老变质基底和花岗岩中的火山机构和隐爆角砾岩筒是矿床分布的有利空间。交织的线性构造是控制火山机构、矿体和矿脉的重要因素。深源物质是成矿的主要物源。
The formation of uranium and polymetallic deposits in this area is closely related to the volcanic activity of J_3-K_1 in the late Mesozoic. Deep tectonic variation zone and local lateral extension are the best environments for metallogenesis. Volcanic structures and cryptoexplosive breccia pillars stacked in the ancient metamorphic basement and granite are favorable spaces for ore distribution. The interwoven linear structure is an important factor in controlling volcanic structures, ore bodies and veins. Deep source material is the main source of mineralization.
