Abstract

Summary

Geological and economic efficiency of regional research of tectonics of oil-and-gas bearing regions of Ukraine, and also researches of geological structures of sedimentary cover, depends on taking into account of all geologic-geophysical information, including quality interpretation of high-precision gravimetric data. As practice shows, morphology of Bouguer gravity anomalies in scale 1:50000 and larger is high-informative for detecting and tracing tectonic zones, faults, and individual structural forms. The transformations of gravity fields allow identifying and tracing local anomalies among other anomalies. Preliminary analysis of frequency and relative depth characteristics of anomalies and also the parameters of the transformations determine the physic-geological content of the localized groups of anomalies. The variants of isotropic and anisotropic combined transformations of averaging, which, in accordance with their frequency and depth characteristics, are intended to detect in the gravity field of isometric or elongated local anomalies of a certain direction and the approximate depth of their sources are presented in the paper. The practical results of the application of these combined transformations are also given.
