Abstract

As you know, quite significant gold resources are concentrated on the territory of the Russian Federation, but despite this, work aimed at expanding the mineral resource base of this most valuable metal, which plays a huge role in the country's economy, is still relevant. The object of this study is the territory of the Vyun gold deposit. The subject of the study is bottom sediments of watercourses in the territory of the Vyun gold ore deposit. The aim of the study is to assess the background ecological, geochemical and mineralogical characteristics of bottom sediments of watercourses in the territory of the Vyun gold deposit at the pre-production stage of its development. The work was carried out within the framework of complex ecological and geochemical studies and was organized in accordance with the methodological approaches and methodological recommendations that are currently relevant today. This article presents the results of studies of bottom sediments of watercourses flowing in the territory of the Vyun field. Elemental analysis of bottom sediment samples from watercourses was carried out by inductively coupled plasma mass spectrometry (ICP-MS).. The mineral composition of the samples was studied by optical microscopy, X-ray diffractometry and scanning electron microscopy. The relevance of research is due to the need to obtain background data on the state of the natural environment of the Vyun field, without which it is impossible to further assess the current ecological and geochemical state of the territory and forecast the environmental consequences of the industrial development of the field. At present, the importance of such work is often underestimated, although it is thanks to the background assessment that it is possible to have an idea of the initial parameters of the state of the territory of mineral deposits. This study has just such a focus and is devoted to assessing the background state of bottom sediments of watercourses in the territory of the Vyun gold deposit (Republic (Sakha-Yakutia))
