Abstract
This data package is an archive of geospatially located and other digital geological and geophysical data covering the Tanami Region and north Arunta in the Northern Territory and Western Australia, a portion of the North Australia Project undertaken to understand elements within the North Australia Craton and its margins. It includes themes for a number of regional scale, 1:250 000 scale, and 1:100 000 scale geological map sheets, mineral locations, geophysical images, company drill hole and rock chip locations, company and Geoscience Australia geochemistry, and interpretations and synthesis derived from the data.

Lineage
1:100 000 scale geological maps published by the Northern Territory Geological Survey were scanned by Geoscience Australia in TIF format and registered to frames in GDA 1994 coordinates. The maps may also be provided in unregistered PDF or JPEG formats. 1:250 000 scale geological maps sourced from the Bureau of Mineral Resources or the Northern Territory Geological Survey. Some maps were digitised under the NTData Project or by the SIMS group within the Australian Geological Survey Organisation. Digital geology is provided for all sheets, however the atest edition digital geology for the Birrindudu, The Granites, Mount Solitaire, Highland Rocks, and Mount Theo sheets have not been completed by the NTGS. The map faces have been scanned and georeferenced as images. 1:250 000 scale interpreted geology for the Tanami and The Granites sheets were obtained from the Northern Territory Geological Survey with graphic attributes, and converted to ArcInfo format. Polygon items do not comply with solgeol layers in the Geoscience Australia Digital Data Dictionary. 1: 500 000 scale geological maps and interpreted geology maps, sourced from Bureau of Mineral Resources mapping were scanned by Geoscience Australia and are provided as registered or unregistered images. The North Arunta Region, May 2004 first edition interpreted geology map, published by the Northern Territory Geological Survey, was scanned and registered to the Albers Equal Area projection noted on the map. Geophysical-dem-landsat images, geochemistry and mineral locations were sourced from Geoscience Australia corporate stores. Exploration company drill holes, rockchip samples and assocatiated geochemistry for the Tanami and Arunta areas were sourced from Northern Territory Geological Survey data bases. Regional interpretations were sourced and produced within Geoscience Australia. For more detailed information on lineage of individual layers, refer to README.TXT files in each directory provided on the DVD.
