GROUND SURVEYS

Geophysical ground surveys for exploration

Strong geophysical expertise

GRM provides ground-based geophysical measurement services that provide information from the first metres of soil to kilometres down into the bedrock. 

The methods are used to investigate the physical properties of the bedrock, such as electrical and magnetic properties, density and elastic properties.

We have a high level of expertise throughout the research process, a high regard for safety, efficiency and experienced staff. In addition, the company offers a very wide range of geophysical services.

    • Measurement of conductivity

    • Exploration for conductive mineralisation

    • Configurations: moving loop, fixed loop, multi loop

    • Transmitters: 4 - 75 kW

    • Sensors: SQUID, fluxgate and induction coil

  • ·      Measuring the Resistivity and Chargeability of bedrock

    ·      2D profile measurements

    ·      3D measurements with multiple receivers on the ground and in holes

    • Deep geological mapping

    • Measurement of variation in bedrock density

    • Geological mapping

    • Mapping the magnetism of bedrock

    • Passive deep electromagnetic method

    • Rock resistivity mapping on a large scale (0 - 3000m)
