Abstract
An electronic map of absolute values of gravity field ( G н ) has been plotted for the territory of Ukraine for the first time with application of combined electronic matrices of Buge anomalies in case of the density of intermediate layer 2.3 g/cm 3 and the values of altitude marks (the Baltic system). The size of unit cell of the matrix is 1´1 km, the error obtained for the map interpolation G н for flat country is ±2,1 mGal. It has been shown that the maps of G н give more complete information on tectonic processes, taking part in the Earth’s crust formation because they reflect combined effects of density and relief-producing factors, which are not taken into account while maps of Buge anomalies are being analyzed. Examples have been given of large lineaments of tectonic origin, clearly visible on G н map and practically unnoticeable on the map of Buge anomalies. Comparison of anomalies of G н and Buge (2,3 g/cm 3 ) in mountain areas (Crimea, Carpathians) gives an idea of hypogenous nature of gravity objects, and large regional differences of anomalies G н , which are as big as 950 mGal within the limits of Ukraine must be taken into account while problems of geophysical ecology and compiling meteorology forecasts are being solved. A necessity is being indicated to introduce maps of G н field to a set of gravimetric materials used for geological-geophysical interpretation. In this connection we propose to introduce in the running regulations for gravity works a demand on presenting a map of observed gravity field as a report.
