Beetaloo Sub-basin magnetic georeference image

Abstract

The dataset was derived by the Geological and Bioregional Assessment Program. Georeferenced TIF image of the magentics of the Beetaloo Sub-basin and adjacent area. Total magnetic intensity (TMI) data measures variations in the intensity of the Earth magnetic field caused by the contrasting content of rock-forming minerals in the Earths crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The 2015 Total magnetic Intensity (TMI) grid of Australia has a grid cell size of ~3 seconds of arc (approximately 80 m). This grid only includes airborne-derived TMI data for onshore and near offshore continental areas.

History

This dataset is a clip of the Total Magnetic Intensity (TMI) Grid of Australia 2015 (sixth edition) for the area immediately surrounding the Beetaloo GBA region. The clip was carried out in ArcGIS software and saves in GEOTIFF format. For more information on the parent dataset please see http://pid.geoscience.gov.au/dataset/ga/89595 .
