л.п.维库洛娃,А.Н.诺维科娃和В.П.柯齐尼科夫古代沉积所形成的黑色页岩层中有几种矿床产于元古代后期的破碎岩系中。该岩系的特征为变质砂岩、变质泥岩、千枚岩复理式互层炭质含量较高。互层中的各种岩石只受到弱区域变质作用(绿片岩相的绢云母—绿泥石亚相等)和局部的热水变质作用。局部的热水变质现象可见到如强片化带,扰乱带及碎裂带。在该区内有两种类型的金矿床。第一种为细脉 л.п. There are several deposits of black shale formations formed by ancient deposits of Vikulova, А.Н Novikkova and В.П. Koznikov. They were produced in the late Proterozoic crushed rock series . The rocks are characterized by metamorphic sandstone, metamorphic mudstone and phyllite complex interbedded carbonaceous matter. All kinds of rocks in the interbedded layer are only affected by weak metamorphism (sericite-chlorite subfacies of the green schist) and local hot-water metamorphism. Local hot water metamorphism can be seen, such as strong sheet with disruption and disintegration zone. There are two types of gold deposits in the area. The first one is vein
