Brief description
Provides regional framework study of regolith and associated landforms over the Tanami region. Datasets are all contained in a GIS - these include regolith-landform units, enhanced Landsat TM imagery, site descriptions and photo links, regolith profiles descriptions (geochemistry and PIMA), drill hole geochemistry, gamma-ray spectrometry imagery, palaeochannels, geochemical sampling strategy maps, surface flow vector maps, enhanced DEMs, erosional scarps and maps showing depth of transported cover.Lineage

Statement: Regolith-landform polygons were compiled from airphotos, satellite and geophysical imagery. Compilation sheet at 1:80 000 scale were scanned, cleaned and attributed using ArcInfo GIS software.
Site data was entered in RTMAP databases and then extracted to make a point attribute file in ArcInfo. Sites were recorded using a GPS with +/- accuracy 70 metres.
Structural lineaments were compiled from Landsat TM, gamma-ray spectrometry and the national 9 second digital elevation model. These lines were scanned and attributed using ArcInfo GIS.
Imaged datasets including gamma-ray spectrometry, DEM, gravity, magnetics and satellite Landsat TM were all enhanced in ERmapper. Images were then converted in band interleaved (BIL) format for inclusion into the ArcInfo, Arcview and MapInfo GIS.
The Geology theme has been compiled from historical datasets and does not reflect current Geoscience Australia standards.
