New wide-band EM system ARMT-5: case study - CSAMT survey at potassium deposit in frequency band 10Hz - 100 kHz

Abstract

Summary The new wide-band EM system ARMT-5 described in the abstract combines features of AMT and RMT devices. It is designed for implementation of a variety of electric survey methods: AMT, CSAMT, CSEM, RMT and CSRMT. Its wide frequency range (0.1 Hz – 1 MHz) enables the applying of this tool for the exploration of depths from first meters up to several kilometers for a broad spectrum of targets. CSAMT survey with this equipment has been successfully applied at the potassium deposit for recovering the geological structure at the depth of 300 meters. Measurements have been done in frequency band 10 Hz - 100 kHz.
