The Gawler Ranges is a massif comprising bornhardts developed on Mesoproterozoic dacite, rhyodacite and granite. The country rocks are subdivided by orthogonal fractures into massive compartments within which are developed sets of concentric arcuate

Some authors consider that linear dunes migrate laterally on a grand scale, much as rivers move across floodplains. Others have concluded that lateral movement is limited in time and space. During ...

[Abstract] Rock doughnuts are annular rims developed around rock basins that intermittently carry pools of water. They are developed in granitic rocks, and in arenaceous and calcareous sediments and in coastal as wells as interior settings. Rock leve

[Abstract] Many of the so-called corestones have been developed from rocky blocks that have been apparently affected by subsurface physicochemical weathering that results in lamination, granulation, and eventually a puggy or stiff clay. The truth is

It is important that technical terms with agreed meanings are used correctly. This applies particularly to words that reflect their etymology. Neglect of this principle distorts information and compromises the discussion, understanding, and value of

The Waddikee Rocks are located on northern Eyre Peninsula. They are unusual because of their migmatitic composition. They are also associated with the fate of the early explorer of the region, J.C. Darke. The hills are upstanding because of the massi

An extensive and composite field of calcareous coastal foredunes was deposited on the west coast of Eyre Peninsula during the Middle and Late Pleistocene. Several islands became linked to the mainland. Rivers that previously had drained to the Great

Contrary to geomorphological convention many landscape elements evidently predate the Neogene. Some are of exhumed origin but many are of etch type and can be dated by means of stratigraphic and topographic data. Most appear to occur in Gondwanan rem
