GEOLOGICAL AND ECONOMIC ZONING BY THE METHOD OF ASSESSING THE POTENTIAL OF SUBSURFACE RESOURCES AS A TOOL FOR RATIONAL SUBSURFACE US
To solve the tasks of forming a program of rational nature management and environmental protection, and in particular the program of rational subsurface use (geological study of the subsurface and the reproduction of mineral resources), it is necessary to provide executive authorities at the federal and regional levels with up-to-date geological and economic information. It is necessary to solve the problems of information support of subsurface users using the capabilities of modern geoinformation systems and remote Earth sensing data. However, due to the high cost of space images, it is currently almost impossible to fully use them over a large area and with the necessary detailing. Geological and economic zoning allows determining and taking into account the balance of interests of the subsurface user and the state when forming territorial planning schemes and choosing the technology for developing a field. This article suggests a method of geological and economic zoning based on the calculation of the potential of the subsurface in relation to the territory of the Central Federal District of Russia. Geological and economic zoning makes it possible to determine for each territorial unit not only the list of promising objects for geological study, but also the order of their commissioning for the most rational development. This approach allows to take into account existing and potential relationships of entities, which leads, on the one hand, to maximize valuation potential of the subsurface, and on the other hand, to the necessity of rational use of the subsurface by sequential exploitation of subsurface potential.

Highiights:
♦ based on the current geological structure and the availability of infrastructure for the development of fields in the Central Federal district, we can distinguish two major geological and economic regions - the Kursk magnetic anomaly and the geological and economic region of Moscow suburbs;
♦ on the territory of geological and economic district of the Kursk magnetic anomaly on the authors’ methodology for assessing the potential of identified subsurface industrial raw material groups: Oskol, Belgorod, Mikhaylovskaya, Voronezh;
♦ according to calculations, the Oskol industrial and raw materials group is the leader within the geological and economic region both in the number of large deposits and in the balance reserves of ore А+В+С, and contains 55.2% of all reserves of the geological and economic region.
