FIELD: physics, measurement.
SUBSTANCE: invention is related to gravimetric exploration and may be used in searching of deposits of ores, hydrocarbons and other minerals. According to invention, profiles are installed parallel or subparallel, two secant diagonal profiles are arranged, ends of which are connected to each other by means of binding profiles, besides, one or more points of these diagonal profiles is matched with points of the main profiles, and reference point is placed into crossing of secant diagonal profiles, area relief effect corrections are made, analytical approximation of measured gravitational field is carried out with preset error, and it is reduced into several horizontal planes, for different heights, by means of solution of reverse linear task, density is determined in every layer between two neighboring planes, and 3D diagram is built for geological medium structure.
EFFECT: provision of higher space resolving power.
