2.3.4 Terraces and floodplains (Glenelg, Wannon Rivers)

Beyond the Grampians, low plateaus or tablelands are characterised by deep lateritic weathered profiles. These are developed over a range of rock types probably in part on a transported cover of Cainozoic age. The domal topography, active stream erosion and evidence of uplifted and deformed Neogene shoreline ridges indicate neotectonic activity. The characteristic (altered from pre-European) vegetation is scattered Red Gum woodland.

These tablelands abut the Grampians forming an apron, mainly to the west. They are differentiated by the degree of dissection, but are also characterised by the underlying geologies such as acid volcanics and a range of geologies including granite, basalt, metasediments and Permian glacial deposits. These constitute the two divisions of the Dundas Tableland, while the heavily dissected Merino Tableland lies to the south on
Cretaceous sediments within the Glenelg Hopkins CMA region.
