Abstract

In this paper the authors consider the influence of the host medium on the morphology of the magnetovariational (MVP) anomaly from a local object with a relative conductivity of the section 10,000 Sm·m and 500 m depth. Conclusions are based on mathematical modeling. The results have shown that the covered rocks are the main cause of a local anomaly distortion. Resistivity changing of bottom layers have a weak effect on local anomaly disturbing. The anomaly of a local object can be isolated as a result of subtracting a regional component from the Wiese matrix of the original field. The express interpretation of MVP data and inversion codes can be applied for the described anomaly.
