Abstract
This data release includes a three-dimensional (3D) geological map of the Cooper Basin region which has been produced from 3D inversions of Bouguer gravity data using geological data to constrain the inversions. It also includes predictions of temperature and temperature uncertainty which have been produced from the 3D map. The 3D geological map delineates regions of low density within the basement of the Cooper and Eromanga basins. These are inferred as granitic bodies, which may act as heat sources. It also delineates the stratigraphy of the sedimentary basins which provide thermal insulation. This release is the second version of the 3D map of the Cooper Basin region. It builds on Version 1 of the Cooper Basin Region Geological map, released in 2009. The 3D map is supplied in Gocad® format as a voxet. The voxet contains the following properties: Geology - defined as lithology number (integer) corresponding to each geological unit in the 3D map: 0 - Air 1 - Surficial 2 - Allaru 3 - Cadna-owie 4 - Westbourne 5 - Nappamerri 6 - Toolachee 7 - Patchawarra 8 - Tirrawarra 9 - Warrabin Trough 10 - Basement (central) 11 - Undifferentiated granite 12 - Big Lake Suite granodiorite 13 - Devonian granite 14 - Basement (northwest) 15 - Basement (southeast) Heat_Flow - Predicted heat flow (in mW/m2) throughout the volume of the map Heat_Production_Rate - input heat production rate (in W/m3) assigned to each geology unit Temperature_degC - predicted temperature in degrees celcius throughout the volume of the map Temperature_Standard_Deviation_degC - standard deviation on the temperature predictions Temperature_Standard_Deviation_percent - standard deviation on the temperature predictions, calculated as a percentage of the predicted temperature Thermal_Conductivity - final thermal conductivity values (W/mK), calculated at the modelled temperature.
