TEM

Where to use

Typically used for locating massive metallic ores. Method is based on conductivity contrast between the conductive metallic ore and resistive host rock. Typical geological structures where the Ground TEM method is applied are: deep deposits, intrusions, massive conductive ores.

Advantages

Ground TEM method is effective for locating the deep conductive deposits. TEM method is effective in guiding the following exploration acts such as core drilling.

Surveys

Separate transmitter and receiver are needed. Transmitting loop is laid on the ground. The receiving 3-component magnetometer is moved on the ground or in the borehole (see Borehole TEM). Two main survey configurations are applied, static loop and moving loop. Loop size is varied according to the target depths. Super conductive magnetometers (SQUID) can be used as receiver to improve the sensitivity.

Equipment

Please, see our comprehensive Ground TEM equipment from equipment listing. If you can’t find desired geophysical or any other equipment from our selection, please let us know. We have excellent connections to rental agencies and pools. Our crew has comprehensive experience of various geophysical equipment.

Data

Client will always receive quality assured raw data from the surveys. Additionally, we are able to do the data processing and modelling work. Reporting to requested level as well as orientation of the client to the survey results will be done as requested.

The final product of ground TEM is usually 3D model of the deposit.
