Notes showing that the estuary of the Derwent was occupied by a fresh-water lake during the tertiary period
Johnston, Robert Mackenzie (1881) Notes showing that the estuary of the Derwent was occupied by a fresh-water lake during the tertiary period. Papers & Proceedings and Report of the Royal Society of Tasmania . pp. 7-21.
Apart from the circumstance that the extensive tertiary
fluviatile and lacustrine formations of Australia have been the
principal sources from which we have derived our rich
treasures of gold and tin in the free state, their study from a
naturalist's point of view is also peculiarly interesting from
the nearness of their deposition to our own time.
Many present may have noticed along the shores of the
Derwent, particularly in the neighbourhood of Sandy Bay,
One Tree Point, and Cornelian Bay, a series of sandy and
clayey beds sometimes of considerable thickness and extent.
They frequently dip irregularly at various angles, and in
various directions, as if they had been much disturbed subsequent
to their deposition, but they are never found at an
altitude of much more than 40 feet above the existing sea
