A new compilation of magnetic data over onshore and offshore Tasmania plus existing geological mapping and gravity data have provided the basis for the production of map illustrating the geometric distribution of the main basement units of the state. Significant aspects of the new interpretation map include: the delineation of the wide-spread sub-surface granite occurrences in Tasmania; identification of more extensive occurrences of Proterozoic rocks than previously known; mapping of the extent of the Dundas Trough and extensive northwestern and southeastern continuations of the Beaconsfield ultramafi rocks; definition of the areal distribution of Mesozoic sedimentary basins; and the control of Proterozoic lineaments, in particular the Arthur Lineament, on the development of the Mesozoic basins.
