Abstract

The Mantung High Plain of the western Murray Basin is a karstic surface of low relief developed on the Early Miocene Mannum Limestone and plausibly interpreted as an example of a perched karstic plain. The Plain is attributed to corrosion planation, i.e. dissolution and collapse down to the Pliocene water table associated first with the ancestral allogenic and exoreic River Murray that then flowed in shallow valley graded to a relatively high regional baselevel, and in later Pliocene times to the estuary that inundated the valley. During the Quaternary the Plain was left high and dry (and converted to the High Plain) by the incision of the Murray and becoming graded to lower baselevels and water tables. Conservation was enhanced by the widespread formation of a calcrete duricrust
