Transient electromagnetic called Time-Domain Electromagnetic (TDEM), is the basic method applied for locating the massive sulphides, problems associated with geological structures, partly in oil-and-gas prospecting (specially to corroborate seismic data). Two variants are in common use: Stationary source and moving source. In stationary source TDEM profiling surveys a large loop is laid parallel to the strike of the formations/ targets and the Receiver is moved along the traverses to record the three components of the secondary induced magnetic field when the strong currents passing in the loop are switched off momentarily. In TDEM sounding the receiver records the transient decaying secondary magnetic field at the centre of the loop coaxially. Sophisticated software for processing profiling and sounding data is commercially available. In moving source both the transmitter and receiver are moving along the traverses.

Application of Transient Electromagnetic Equipment:

Transient electromagnetic (TEM) equipment is commonly used in various applications for subsurface exploration and surveying. Here are some of the key applications of transient electromagnetic equipment:

Mineral Exploration: TEM equipment is widely used in mineral exploration to locate and map underground mineral deposits. By transmitting electromagnetic pulses into the ground and measuring the resulting electromagnetic response, TEM surveys can provide information about the conductivity and resistivity of subsurface rocks. This data helps geologists identify potential mineral-rich zones.


Groundwater Exploration: TEM surveys are also employed for groundwater exploration and mapping. The equipment can determine the depth, thickness, and quality of aquifers by measuring the electrical properties of the subsurface. This information is crucial for water resource management, well siting, and optimizing groundwater extraction.


Environmental Studies: TEM equipment plays a vital role in environmental studies, particularly in assessing geological and hydrological conditions. It can be used to investigate contamination plumes, map subsurface structures, and identify potential pathways for pollutant migration. This helps in designing effective remediation strategies and monitoring the effectiveness of cleanup efforts.
