Deep structure geo-density models in the area of local gravitational anomalies in the north of the Volga-Ural anteclise

Detailed geological and geophysical studies discovered intensive local gravimetric anomalies (Frolovskaya, Chetdinskaya, Lokchimskaya, Kynmemtila and others) in the south of the Komi Republic, which were promising for the discovery of bodies of the basic (ultrabasic ?) composition in the production of geological and geophysical works [8, 9]. Within them, a database of XYZ (recorded and extrapolated) in arbitrary units of the gravity field and their rectangular coordinates was created in the Microsoft EXCEL program, with more than 1600 values, and formed grid files, based on them, formed the basis for calculations in the Golden Software SURFER program for constructing models of the deep structure. As a result of the interpretation of the gravity field, geological and geophysical models of the deep structure
