| Popis: | The relevance of the study is caused by the need in data on the soil background states in the territory of the gold ore facility as well as in knowledge of relationships between the mineral and geochemical features of the deposit soil cover. The purpose of the research is to detect mineralogical and geochemical features of the soil cover of Vyun gold deposit territory at the pre-operational period of its development. Object of the study is soils of the territory of Vyun gold deposit. Factual materials and research methods. The factual material was obtained by employees of the Department of Geoecology and Geochemistry of the National Research Tomsk Polytechnic University in 2017 in the course of research work. The paper presents results of the study of the Vyun gold deposit territory based on 19 soil samples obtained at that time. The work was carried out by standard methods in accordance with the regulation documents. The elemental composition of the soils including 55 chemical elements was determined by the mass spectrometry method with inductively coupled plasma at the analytical chemical certified center «Plasma» (Tomsk). Mineral composition of soils was determined using optical microscopy, X-ray diffractometry and scanning electron microscopy on the basis of the International Scientific and Educational Center «Uranium Geology». The results were processed using modern software (Microsoft Excel, Statistica, Corel Draw, etc.). Results. The mineralogical and geochemical features of the soils in Vyun gold deposit territory have been determined. The relationship between the mineral composition of the ore zone and the soil geochemical characteristics was established. The data were obtained on the increased contents of gold and elements-satellites of low-sulfide gold-quartz mineralization, namely arsenic, silver, antimony, their contrasting scattering halos were determined, which can be used in the practice of further prospecting work. |
