Controversial points in the methodology of modern interpretation theory of gravity anomalies and the ways to resolving contradictions

Balk, P. I.

2014 Izvestiya, Physics of the Solid Earth

doi:10.1134/S1069351314020025

Abstract The fact that most of the basic points in the methodology of interpretation theory of gravity anomalies are inadequate to the targeted intention—to extract the maximal volume of reliable information about the sources of the field—has barely been noticed so far. It is established that...
