Very low frequency electromagnetic prospecting method—A few field applications in India

Proceedings of the Indian Academy of Sciences - Earth and Planetary Sciences Aims and scope Submit manuscript

Abstract

The very low frequency electromagnetic prospecting equipment measures different space and phase components of the electromagnetic field in the frequency range 15–25 kHz emanating from distant naval radio stations. The field application of the equipment designed and constructed for this purpose has demonstrated the usefulness of the investigations in groundwater and geological mapping. The amplitude measurements necessitate correction of the diurnal variations of the electromagnetic field at the observation point.
