Structuration, Petroleum Prospectivity and Potential of Northern Tasmania, Australia

The island of Tasmania is situated off the southeastern coast of Australian continent. Most of the central and eastern part of this island is covered by the Tasmania Sedimentary Basin which is an erosional remnant of a larger shallow intracratonic (epicrotonic) basin, consisting of sedimentary successions deposited in the Late Carboniferous to the Late Triassic and intruded heavily by the mid - Jurassic dolerite rocks. The basin was uplifted and deformed in the Late Cretaceous to the Early Tertiary times. It is also enderlain by the deformed Ordovician to Early Devonian sedimentary and older crystalline basement rocks.
