CSAMT
Surveys
The CSAMT technique involves the measurement
of electric and magnetic fields at a distance of between 3 to 15 km from
a grounded dipole transmitter source. The measured quantities are
apparent resistivity and phase difference between the transmitted and received
waveforms. This method has greater lateral resolution and depth penetration
than the TEM technique with station separations usually between 10 and
200 metres.
CSAMT has been employed successfully in mineral
and petroleum exploration, mapping of geothermal zones and groundwater
and environmental mapping. It is not ideally suited to areas of thick,
conductive overburden as occur in parts of Australia.
