This Bulletin covers the offshore region west of Tasmania. The western margin of Tasmania, an area of 100,000 sq km contains a thick cover of Late Mesozoic and Tertiary sediments. Most of this sedimentary wedge lies within the Sorell Basin, an extensional passive margin basin that formed as part of the Southern Rift System in the Late Jurassic-Early Cretaceous. See Section 2 - Regional Geology for discussion of the regional geology and development of the western margin. Section 7 - Environmental Features discusses the marine environment and climatic and tidal effects on the western margin. The Sorell Basin Petroleum Prospectivity Package concentrates mainly on the northern part of the basin containing the King Island and Strahan Sub-basins. It is primarily in these two sub-basins that there is sufficient well and seismic data to assess the prospectivity of the Sorell Basin. See Section 6 - Prospectivity for the discussion of the basin's prospectivity.
