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. {"type": "Polygon", "coordinates": [[[144.0, -44.0], [150.0, -44.0], [150.0, -40.0], [144.0, -40.0], [144.0, -44.0]]]} 144.0 150.0 -44.0 -40.0 AU-TAS Earth Sciences External Publication Published_External Scientific Journal Paper Link to Publication documentDigital Link to Publication HTML Unnamed resource documentDigital HTML
