Abstract
Solid geology of the Tennant Creek to Mount Isa (TISA) area comprises four layers, namely: Mesozoic, Paleozoic, Neoproterozoic and Pre-Neoproterozoic. This is the first staged release of Geoscience Australia's national time based solid geology mapping program commenced under the Federal Government’s Exploring for the Future program. This product will be updated as the solid geology program progresses. The solid geology layers were produced by interpretation of magnetic and gravity datasets and reference to available solid and surface geology maps, particularly GA's 1:1 M scale surface geology of Australia (2012), published 1:250 k scale map sheets, and the Northern Territory Geological Survey's solid geology maps of the Pine Creek (2005) and Tennant regions (2004). Drill hole constraints have been utilised where possible. Interpretations were compiled at 1:250 k scale and the final product is best utilised at this scale. Notably this release reveals the concealed extent of the Cambrian basalts of the Kalkarindji Igneous Suite, which extend over a large part of the TISA area.
