Abstract

The relevance of the research is justified by the need in data on the state of natural surface waters in the territories of gold mining enterprises located in the permafrost zone of the subarctic belt. The purpose of the research is to identify the geochemical properties of natural waters in the territory of Vyun gold deposit at the stage of pre-production development. Object: surface waters of the Vyun gold deposit. Factual materials and research methods. The factual material was obtained as a result of research work carried out in 2017 by the Department of Geoecology and Geochemistry of National Research Tomsk Polytechnic University. This paper discusses the study of watercourses in the territory of Vyun gold deposit on the basis of 13 water samples taken in the area. The samples were taken and processed using standard methods in accordance with regulation documents. The elemental composition of water was determined in the accredited Problems Research Laboratory of hydrogeochemistry of the Scientific and Educational Center «Voda» of the National Research Tomsk Polytechnic University. Contents of 71 chemical elements were determined by the method of inductively coupled plasma mass spectrometry. A number of methods were used for establishing the hydrochemical characteristics of the waters. More specifically the samples were analyzed by following methods: titrimetric; potentiometric; conductometric; gravimetric; photocolorimetric; spectrophotometric; by ion chromatographic. The calculation methods and codes developed in Scientific and Educational Center «Voda» were used as well. The results were processed using Microsoft Excel and Statistica. Schemes and diagrams were performed by the graphics editor Corel Draw. Results. The geochemical features of the natural watercourses of the Vyun gold ore deposit area under permafrost conditions were specified. The presence of contrast anomalies of chemical elements represented by arsenic and mercury was established. These elements are satellites of low-sulfide gold quartz mineralization.
