Comparison the readings of gravity field and it's gradient potentialThe problem of studying the deep structure of the earth's crust is one of the strategic directions of geophysical research, ensuring the development of Earth sciences.Therewith, gravimetry is one of the main methods for studying the structure of the earth's crust.This study is associated with the concepts of gravitational field's potential and gradient of the underground anomaly.Solving the inverse problem of restoring density of the underground anomaly, thorough analysis of the direct problem plays an important part.This study analyzes the characteristic features of the readings of anomaly gravitational field's potential and gradient.Based on the results obtained by the author, it has revealed and verified the necessity of choosing a gradient as the boundary conditions of the direct problem, which will significantly improve the inverse problem calculations results -finding the density of anomaly.This research demonstrates quantitatively that anomaly gravitational field's gradient more accurately describes the anomaly, compared to the gravitational field's potential.
