Abstract
ABSTRACT
For the interpretation of gravimetric and magnetic maps two types of master curves are proposed: firstly those which apply both to the vertical gradient of g and to the pseudo gravimetric gradient obtained by reduction to the pole of magnetic maps; and secondly those which apply direct to magnetic anomalies.
With regard to the first type of master curve, the principle and the advantages of the reduction to the pole are discussed. In the last part of the paper it is shown how a set of master curves, calculated for two‐dimensional east‐west striking structures, can also be used for the interpretation of two‐dimensional structures of arbitrary direction of strike. Practical examples of application are given.
