Audiomagnetotelluric (AMT)
Audiomagnetotelluric (AMT) surveys use natural electrical energy, primarily from electrical storms that propagate through the atmosphere. AMT surveys are effective in resistivity imaging to depths of up to 1 km. The AMT method has seen significant improvement over the last decade, and the method can produce accurate 2D or 3D models for many mineral exploration applications where moderate depth search is required and where resistivity variation is expected.
