Mangetics

Applications

Magnetic surveys measure small, localised variations in the Earth's magnetic field. The magnetic properties of naturally occurring materials such as magnetic ore bodies and basic igneous rocks allow them to be identified and mapped by magnetic surveys. Strong local magnetic fields or anomalies are also produced by buried steel objects. A broad range of applications of ground magnetic surveys are:

  • Accurately mapping archaeological features
  • Mapping basic igneous intrusive rocks & faults
  • Evaluating the size and shape of ore bodies
  • Identify geologic bedrock features such as mafic dikes or geologic contacts
  • Delineate areas of ferromagnetic
  • Finding buried steel tanks and waste drums
  • Detecting iron and steel obstructions
  • Locating unmarked mineshafts
  • Locate underground storage tanks (USTs)
  • Locate buried drums
  • Delineate landfill perimeter
  • Identify locations of historic structures
