The purpose of this data package is to provide end-users with the GIS datasets and geophysical raster grids used for the 2010 modelling of mineral potential in the Musgrave Province region, which includes the APY (Anangu Pitjantjatjara - Yankjantjatjara [Aboriginal]) Lands. This region spans parts of South Australia, Western Australia and Northern Territory, and consequently the subject data package contains merged subsets of open-file SA, WA and NT spatial data, sourced from the Geological Survey of Western Australia (GSWA), Northern Territory Geological Survey (NTGS), Geological Survey of South Australia (GSSA), and Geoscience Australia. The data package includes the following GIS layers: • merged surface geology, at scales from 1:50,000 – 1:250,000; • 1:2 million scale surface geology; • mineral occurrences; • structural interpretation of Total Magnetic Intensity (TMI) data, made by consultant Leigh Rankin; • drillhole stratigraphy; • whole rock, soil and stream sediment geochemistry; • TMI grid (clipped from Geoscience Australia's national TMI grid); • gravity grid (constructed by GSSA); and • localities and roads (clipped from Geoscience Australia's national 1:250k topographic map sheet coverage, Series 2).
