Local Assessment of Ore-bearing Intrusive Formations Based on the Modern Techniques of Interpretation of Geopotential Fields

A. S. Dolgal, O. A. Dudin

Abstract


The article shows the effectiveness of the modern techniques of gravity and magnetic data interpretation in geological difficult terrain conditions of the northwest of the Siberian platform. It describes the results of local assessment of the deep-laying intrusive bodies bearing a copper-nickel mineralization obtained with the use of probabilistic and statistical methods, and an interpretative tomography transformation.

Keywords
