SFUHDLAbstract
One of the basic problems of the gravity exploration is the methodology problem of the reducing of gravity data, actuality of which has increased during last ten-year periods in connection with raising of field measurement accuracy with gravimeters and determining of geographic coordinates and absolute elevations of gravity stations. The modern approaches to the reducing gravity data problem in the ground gravimetric explorations are discussing in the article. During last ten-year periods the methodologies of correction calculation for gravity vertical gradient in free-air (Faye's correction) with take into account ellipticity of the Earth and excess mass adjustment calculation with take into account spherical Earth are widely used. The Bouguer and Glenny anomalies calculation was proposed to execute for the geoid model "Standard Earth" for the most full account of the conformities of normal gravity field and its vertical gradient changes not only by latitude but also longitude. Possible approaches for such methodology realizing were considered.
