Mineral Exploration Geophysics projects - Zonge International

CSAMT refers to controlled source audio-frequency magnetotelluric, a frequency EM survey method using a remote signal source. An EM signal is generated by a grounded dipole while electric-field and magnetic-field measurements are made at a grid of receiving stations. Subsurface resistivity values are later calculated from these measurements.

Exploration geophysics - Wikipedia

Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties.
