New outcrop geology of Northwest Queensland
16 August 2004
A new 1:1 million scale digital geological dataset of Northwest Queensland, western Cape York and Torres Strait, compiled by Geoscience Australia and including data from the Geological Survey of Queensland (GSQ) is now available for free download. The new dataset is the fourth instalment in a new national compilation of the Surface Geology of Australia at 1:1 million scale. Datasets for Tasmania, Victoria and southern Queensland are already available.
The new Queensland dataset covers the area from the Mount Isa Inlier, Murphy Tectonic Ridge, and eastern McArthur Basin, north to Torres Strait. The data set was compiled mainly from regional 1:500,000 scale maps but complemented with some second generation 1:250 000 scale geology. Cainozoic geology in the area of Mount Isa was subdivided using images of enhanced Landsat TM and gamma-ray spectrometric data. Xstrata Copper Exploration is gratefully acknowledged for providing access to gamma-ray spectrometric data coverage of the Mount Isa Inlier.
