Abstract

Summary

In this work an estimation of the affection of current decay time duration on TEM curves by means of mathematical modelling is described. Horizontally layered medium with vertical cylindrical inhomogeneity is taken as a geoelectrical model.

Kimberlites in host rocks form zones of increased conductivity, which represent a criterion of identification of search objects and determine advantage of using the methods of electromagnetic prospecting. In particular, TEM is used for solving search and parameterization tasks for kimberlite objects. However, the effectiveness of TEM application directly depends on the selection of a correct measurement technique, including current decay time duration in the source.

The question arises as to how current decay time duration in a source affects the amplitude of the anomaly caused by the local conductive subvertical object and what time ranges of turn-off current decay time duration are acceptable. This article is devoted to the study of this problem by means of mathematical modelling
