Abstract

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 a 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 ultramafic 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.
