The Neoproterozoic to Paleozoic Thomson Orogen is a major component of the Tasmanides of eastern Australia that extends through large portions of central and southwest Queensland and northwest New South Wales. Much of the Thomson Orogen is buried under younger sedimentary basins (some up to several kilometres thick) and regolith cover, making it one of the most poorly understood elements of Australia’s geology. As a result, the mineral potential of the region is also poorly defined. The Southern Thomson Project (the Project) is a collaborative investigation between the Commonwealth of Australia (Geoscience Australia – GA) and its partners the State of New South Wales (Department of Trade and Investment, Geological Survey of New South Wales – GSNSW) and the State of Queensland (Department of Natural Resources and Mines, Geological Survey of Queensland – GSQ). The Project aims to better understand the geological character and mineral potential of the southern Thomson Orogen region, focusing on the border between New South Wales and Queensland, by acquiring and interpreting multi-disciplinary geophysical, geochemical and geological data. The primary intended impact of this work is to provide the mineral exploration industry with pre-competitive data and knowledge that reduces risk and encourages mineral exploration in the region.

Geoscience Australia defines a sample as a feature observed, measured or collected in the field. A specimen is a physical individual sample collected during the field work. This data set represents a subset of all Sampling data held by Geoscience Australia that have been collected as part of drilling activities (ie relate to Australian Boreholes). The data will be utilised by other data domains by providing Sampling context to various Observation & Measurement data.
