Ground Magnetics

Fender Geophysics has years of experience applying ground magnetic surveys to a range of projects in varying environments from large mineral exploration surveys to the detection of buried metal objects such as steel drums or UXOs.

Magnetic surveys are typically employed in mineral exploration to identify metallic subsurface structures either directly (ore), indirectly identifying gangue minerals associated with the ore itself or magnetic destruction in alteration zones. It is a fantastic mapping tool.

In urban and industrial applications, magnetic methods  allow the identification of structures such as:

  • piles
  • reinforced concrete foundations
  • underground storage tanks and drums
  • hazardous materials related to waste rock
  • geoforensics

Magnetic surveys are also widely used in the coal fields to delineate coal bearing sequences as the sediments containing the coal beds commonly have a low magnetic susceptibility in contrast to the country rock.

Fender specialises in utilising caesium vapour magnetometers with its high degree of precision to suit your survey requirements.
