| Popis: | Bentonite clay is an important natural material, widely used in many industries. The purpose of this article is to analyze the mineral resource base of bentonite clays in Russia. The data on reserves of deposits, the degree of their development and production volumes are given. The composition and uses of the main developed deposits of bentonite clay in Russia are characterized. A comparative analysis of the reserves and production growth of bentonite over the past decade is carried out. A brief description of the world situation is given, and the mineral resource base of the CIS countries is considered. Since the quality of raw materials, its properties and reserves directly depend on the conditions of origin, a characteristic of the geological and tectonic position and genesis of the bentonite clay deposits of Russia is given. Bentonite-bearing provinces with favorable conditions for the formation of bentonite deposits with volcanogenic-sedimentary genesis are considered. The most promising regions are proposed for the purposes of expanding the mineral resource base of bentonite materials. This work is the result of the authors’ own geological works at various deposits of bentonite clays in Russia, the near and far abroad, as well as the study and interpretation of published materials on this subject over the past decades. |
