Tell us some geological problems that can be solved by VLF-EM
method?

The VLF method is suitable to address problems in which the target is a conductive sheet-like feature that is more or less vertically-oriented and found in a resistive host rock. A suitable application is mapping of faults and fracture zones in cristalline basement. Generally speaking, the ideal depth of investigation is 10-100 m, but this depends of course on the actual conductivity of target and host.
