Abstract

The results of geochemical studies of soils and anthropogenic grounds within the territory of the large Pioneer gold ore deposit developed in the Amur Region are presented. Using the enrichment indices for the soil and ground cover of the Pioneer deposit territory, the following pollutant elements were determined: As, Sb, Mo, Bi, W, S, Cd, and Pb. Using the methods of mathematical statistics, the background contents of As, Sb, Bi, Mo, W, S, Cd, and Pb in the technogenically transformed territory at the sampling time accounted for 63, 8.84, 0.69, 3.54, 4.19, 529, 0.11, and 36.5 mg/kg, respectively. The exceedance of background values for As, Sb, Bi, Mo, W, and S is caused by the natural metallogenic features of the territory. It has been established that the sources of metal emissions into the environment are mining facilities and structures of the mining complex: quarries, waste dumps, heap leaching areas, gold extraction plant, and tailings dumps.

评估先锋金矿床（上阿穆尔州）技术改造区域的土壤覆盖层地球化学成分

本文介绍了阿穆尔河地区大型先锋金矿床境内土壤和人为土壤地球化学研究的结果。利用先锋矿区土壤和地被物富集指数，确定了污染元素As、Sb、Mo、Bi、W、S、Cd和Pb。采用数理统计的方法，采样时技术转化区As、Sb、Bi、Mo、W、S、Cd、Pb的背景含量分别为63、8.84、0.69、3.54、4.19、529、0.11、36.5 mg/kg。As、Sb、Bi、Mo、W、S的背景值超标是由本区的自然成矿特征所致。已经确定，进入环境的金属排放的来源是采矿设施和采矿综合体的结构：采石场、废物倾倒场、堆浸出区、黄金提取厂和尾矿倾倒场。
