综合地球化学研究的基本任务是研究局部的(矿床)的和区域的(矿区)成矿岩浆系统外生地球化学富集场的成分、结构和发育特性,并与内生地球化学富集场进行比较。本项研究工作是在俄罗斯东北部的二个大矿区进行的。这些地区的成矿作用是由晚白垩世岩浆作用和热液作用引起的,形成了含金—银(Au—Ag)建造和含银—多金属(Ag—Pb)建造。广泛分布有分散无工业价值的硫化物(Zn—Pb)矿化。对杜卡特地区来说,典型分布有锡-银(Sn—Ag)和锡-稀有金属(Sn—W)矿化,而Au—Ag矿化主要为银矿化型。
The basic task of integrated geochemical research is to study the composition, structure and development characteristics of the exogenic geochemical enrichment fields in the ore-forming magmatic system of the local (ore deposits) and regions Compare The research work was carried out in two large mining areas in northeastern Russia. The mineralization in these areas was caused by Late Cretaceous magmatism and hydrothermal interaction, resulting in the formation of gold-silver (Ag-Ag) and silver-metal-rich (Ag-Pb) Widespread distribution of non-industrial value sulfide (Zn-Pb) mineralization. For the Ducati region, tin-silver (Sn-Ag) and tin-rare metal (Sn-W) mineralization are typical, while Au-Ag mineralization is mainly silver mineralized.
