Abstract

The role and value of economic minerals (nonmetallic) in the global economy to a great measure depend of new types of of minerals and consistence with increasingly more stringent standards imposed on end products. This article offers the scientific and practical evaluation of formation of economy minerals reserves and resources in Karelia in historical time, starting with saltpans and mica field development to discovery of large commercial-value deposits of nonmetallic materials (cyanite, muscovite–garnet, graphite, carbonate and sulphur pyrite ores, raw material supply base for creaming and glass industry, schungite development, evaluation of quart potential, which was of critical importance for the economy inside the modern territory of the republic). The obtained knowledge on formation of mineral deposits and manifestations of economic minerals and rocks with high content of magnesium, alumina, carbon, feldspar, fluorine, phosphorus and titanium makes it possible to set prospects for high-aluminous and high-magnesian ore, carbonaceous and quartz materials (quarts and quartzite), feldspar and muskovite materials. Solution of scientific and applied problems connected with evaluation of potential of economic minerals is based on the key preamble any kind ore is of no use until geologists, technologies and miners draw an expert’s conclusion on the ore applicability for marketable production at the level of current standards, which complies with the notion of subsoil accessibility. In this regard, the mineral raw materials supply base of the Republic of Karelia has important economic value, and it efficiency depends on creation on high technologies of the 21st century.
