Title: The Cooper Basin 3D map Version 2: Thermal Modelling and Temperature Uncertainty


Custodian: Geoscience Australia

Jurisdiction: Australia



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.
