Geothermal gradients and heat flow in Australian sedimentary basins
Geothermal gradients in Australian sedimentary basins have been calculated from data obtained from water bores in the Great Artesian Basin and oil exploration wells. The data are subject to several types of systematic error, but statistical trends have been extracted, using values of thermal conductivity obtained from sediment compaction models. Estimates of heat flow from the Great Artesian Basin are consistent with the configuration of the major aquifer systems. Oil well data confirm the regional trends obtained from previous investigations, but previously recognised anomalies in southeast Australia are no longer evident. Temperatures at a depth of 40 km range from 320°C to 380°C for the Precambrian terrain and from 470°C to 550°C for the Phanerozoic . These results are modified by sediment cover. A 1 km thickness causes additional heating, with temperatures raised by 16-40°C.
