A grid of the Residual Magnetic Intensity (RMI) for the Bathurst Megatem Aerodat survey, reprocessed and projected to NB Stereographic Double, NAD83.
A grid of the Residual Magnetic Intensity (RMI) for the Bathurst Megatem Aerodat survey, reprocessed and projected to NB Stereographic Double, NAD83.This dataset represents the Residual Magnetic Intensity (RMI) derived from the Bathurst Megatem Aerodat airborne magnetic survey. RMI isolates shorter-wavelength magnetic responses by removing the regional magnetic field from the microlevelled TMI. This enhances local geological and structural features such as contacts, faults, and magnetite-rich zones. All grids have been reprojected from NAD83 UTM Zone 19N to NB Stereographic Double, NAD83.Residual Magnetic Intensity (RMI) represents the shorter-wavelength component of the magnetic field obtained by removing the broad regional magnetic trend from the microlevelled total magnetic intensity (TMI). By subtracting this long-wavelength background, RMI isolates local magnetic responses associated with geological contacts, faults, dykes, alteration zones, and magnetite-bearing bodies, making it a powerful tool for detailed structural and lithological interpretation.Data created Sept 2025.
