Geological mapping

Geophysics (and, in particular, EM methods) has been used for geothermal exploration for some time, designed to map the electric properties of the geology at depth. Techniques such as ground MT provide good depths of investigation and resolution, but at a very high cost. A new technology is now available that provides the ability to cost-effectively map large areas, while detailing the geological structures at depths. The ZTEM system uses naturally occurring Afmag magnetotelluric fields as the source of the primary fields. The ZTEM offers clients the ability to survey large areas and map the structural and electrical properties at significant depths—all at a cost-effective price. The advantages of using ZTEM solution is its ability to provide valuable geophysical data covering large areas, without the ground restrictions and permitting requirements that are needed with MT.
