Several evidential layers calculated from the national-scale gravity anomaly map of Australia (Geophysical Acquisition and Processing Section, 2020) are provided here. This directory includes GeoTIFF grids of Bouguer gravity, the horizontal gradient magnitude of the Bouguer gravity, the Bouguer gravity upward continued 30 km, and the horizontal gradient magnitude of the upward continued gravity, The directory also includes shapefiles of locations that trace the maxima of the horizontal gradient magnitude of the gravity and of the maxima of the horizontal gradient magnitude of the upward continued gravity. Otherwise known as “worms”, the points tracking the maxima mark the edges of shallow density sources (in the case of the Bouguer gravity) and deeper density sources (calculated from the upward continued gravity). The shapefile of worms also includes attribute fields related to the steepness of the gradient and to the trend or strike of the gradient. The reader is encouraged to read the metadata specific to each data layer for details related to the calculation and derivation of each gravity database.
