Complex geophysical interpretation of the conductivity anomaly around Irota

Abstract

In the Cserehát region (NE Hungary), in the vicinity of Irota and Gadna villages an indication of sulfide mineralization is well-known. In order to delineate the ore mineralization, magnetotelluric (MT) measurements were performed which proved the presence of conductive anomaly. This anomaly can only be interpreted reliably with the survey results of other geophysical methods. The potential field methods demonstrated gravity and magnetic anomalies, the seismic survey pointed out important structural elements, mainly faults. The MT data were processed by 2D and 3D inversion techniques as well. The aim of this study is the synthesis of information which originate from different surface geophysical methods.
