- Аннотация: Satellite gravimetry is recognized now as a powerful and reliable tool for regional tectono-geodynamic zonation. Regular observation grid and comparatively high accuracy (1-1.5 mGal) of satellite gravity data retracked to the Earth’s surface (together with other kinds of gravity observations) makes these data indispensable instrument for examination of deep geological-geophysical features (mainly, Earth crust and upper mantle). Accomplished satellite derived gravity measurements (tens and hundreds of millions of observations) may be considered as ‘big data’ because of their volume and variety. For comprehensive analysis of these data, different methodologies can be applied: entropial and information transformations, computing of various derivatives, coherence features and multistatistical characteristics, inverse probability and advanced downward continuation, etc. Effectiveness of the satellite regional gravity analysis is demonstrated on numerous examples from the Eastern Mediterranean, South Caspian Sea and African-Arabian region. It was proposed that increasing satellite derived gravity data accuracy during nearest five years will allow to extend the circle of solvable physical-geological problems.
