Abstract

Tasmania, a small geological outlier of Eastern Australia,
offers a highly interesting field to the geological student.
It must, however, be conceded that its physical history in
pre-Cambrian and early Palaeozoic times can only be dimly
guessed at. In later Palaeozoic times, the conditions appear
to have been insular; in the Mesozoic, there was evidently
a connection with the great Gondwana continent, which
sank beneath the Indian Ocean prior to the Tertiary period.
The greater part of the island has since remained above sea-
level.
