| Abstract | Most published maps of Australian hot rock plays or estimated temperature of basement at about 5,000 m show Tasmania as relatively cool and hence perhaps geothermally unprospective at those depths (eg Holgate and Chopra, 2004). This situation is an artefact of several things, including a) the dataset being largely compiled from hydrocarbon exploration and other sources which did not have geothermal mapping as their primary purpose, b) incorrect assumptions being made on the estimate of depth to geothermal basement in Tasmania and c) the use of temperature gradients as a primary tool for estimation of basement temperature. |
