曾研究了特殊的透镜状一层状铀钼热液矿床,该矿床分布在由中泥盆纪沉积层组成的短背斜的缓倾斜翼部。围岩(从下向上)为:石英斑岩的凝灰岩,混杂成分的火山—沉积层及玢岩。火山—沉积层中有两层粘结性凝灰岩含矿化,下层埋藏在砂岩和砾岩中,上层复盖在砂岩上。并为火山—沉积层的顶部。矿区中广泛出现断裂,在断裂切割凝灰岩

A special lenticular layered uranium-molybdenum hydrothermal deposit has been studied, which is located in a gently inclined wing of a short anticline consisting of sediments from the Middle Devonian. Surrounding rocks (from the bottom up) are: tuff of quartz porphyry, volcanic-sedimentary layers of mixed components and pluton. There are two layers of cohesive tuffs in the volcano-sedimentary layer that are mineralized, the lower layers buried in sandstone and conglomerate, and the upper layers covered in sandstone. And for the volcano - the top of the sedimentary layer. There are widespread fractures in the mining area and the tuffs are cut at the fracture
