The computer automated system is aimed at the study and development of methods of interpreting data of gravity and magnetic fields in the exploration of mineral deposits.
Examples are presented that take into account all the a priori information about the physical and geometric parameters of anomaly-creating objects. A three-dimensional algorithm of gravity selection using an approximation model in the form of a three-bar structure was applied for the territory of the Torgai oil-and-gas-bearing region of the Republic of Kazakhstan, where oil deposits are discovered, and oil and gas shows are recorded in wells and for gabbro-anorthosite massifs of the central part of the Korsun-Novomyrhorod pluton of the Ukrainian Shield. In the first example, the contours of promising areas for conducting direct hydrocarbon searches were obtained. In the second, gabbro-anorthosite bodies were selected and outlined in the upper part of the section, and the depth of their distribution was established. These models can be used to obtain additional reliable geological information.
