Abstract
A gravity survey over Great Lake on the central plateau of Tasmania shows that the structure of the dolerite that intrudes gently dipping Permian and Triassic sediments has appreciable thickening under the northern end of Great Lake and by means of alternate dykes and sills the dolerite moves up and out from the central feeder. This structure facilitates the formation of grano‐phyre over the dykes. The Great Lake intrusion is not unique but a typical form for the Tasmanian dolerite.Keywords
