An alternative technique for gravimetric data processing using approximations of the gravity anomaly field by the reduction surface is described. The approach peculiarity is the representation of reductions in the form of regional trend, where the correction for an interbedded layer is excluded without a certain density value. The field approximation algorithm is based on the least squares method. The results of research, conclusions and recommendations for the gravity anomalies at other geological exploration targets are presented.

Keywords: gravity prospecting, gravity anomaly, approximation, least squares method, density of interbedded layer.
