Distribution of felsic intrusive rocks based on north Queensland solid geology map.Total thickness of sedimentary basins estimated from drill hole data,potential field geophysical data, seismic data and the SEEBASE dataset.
Thermal resistance estimated by integrating thermal conductivity withdepth to a total depth of 5 km.
Potential for hot rock geothermal resources based on weighted summation of inputdatasets (shown in insets). Figure shows calculated hot rock potential. Whiteframe delineates the spatial extent of the area assessed. See text (Huston, 2010)for more information and references.
