∆Т curves transformation for comparison with ∆g curves

Abstract

The importance of simultaneous use of magnetic and gravity anomalies in the study of geologic structure is well known. In the study of regional geology is usually used data from aeromagnetic surveys and maps (or curves on the profiles) of ∆Т and ∆g are compared. Comparison of these data is complicated by two circumstances: 1) the shape of the ∆Т curves is strongly influenced by oblique magnetization to such an extent that under known conditions the ∆Т curves are more similar to the second derivatives of the gravitational potential Uxzv. than to Uzz; 2) the analytical expression of ∆Т is a derivative of the gravitational potential one order of magnitude higher than ∆g. The above difficulties can be eliminated. Let us consider the first question.
