A study of the regional gravity field component in the Urals and adjacent territories

A method is proposed for extracting the regional component of the gravity f ield in the construction of density models of the Earth's crust from profil e data. The regional component of the anomalous gravity field is obtained i n several regional intersection areas of the Urals and adjacent platforms. The most important feature of the inferred regional fields is the presence of an appreciable low over basic structures of the Urals as compared with a djacent platforms.
