Abstract

Mineral-raw materials base of nonmetallic mineral resources of Central Black Earth region includes many types of minerals, the most popular of which are used in the construction industry. These are Precambrian crystalline rocks, especially granites for obtaining high-strength crushed stone, as well as chalk and limestone for cement production, sands as aggregates for concrete and road construction. There are prospects for the production of deficient ballast gravel from the Devonian basalts. There are no restrictions on the reserves of brick-tile, siliceous and expanded clay raw materials. Deposits of ceramic high-melting clay in the region are sufficient to provide enterprises of the region for many years, while reserves of refractory clays and prospects for their growth are limited. In connection with the exploration of the first deposit of secondary kaolins and the quartz sands in the Mamon thickness of the Devonian that encloses them, considerable opportunities exist for the production of kaolin and glass products in the region. Considerable reserves of the molding, as well as sorption raw materials represented by bentonite clays of the Paleogene and Neogene, zeolite-containing siliceous rocks of the Upper Cretaceous. The existing deposits of agronomic raw materials (nodular phosphorites and glauconite-containing sands), taking into account the extensive agricultural land in the region and deficit of mineral fertilizers, can be involved in the development. The possible development of large copper-nickel deposits in the south of the Voronezh and titanium-zirconium deposits in the Tambov regions will increase significant reserves of non-metallic raw materials in overburden and enclosing rocks. These are basalts for secondary kaolins, chalk, glauconite-containing sands, brick loams, phosphorites, siliceous rocks. Explored deposits are situated extremely uneven, their clusters tend to large industrial centers, for the development of which required a variety of mineral raw materials.
