2. Western Uplands (WU)
2.1.1 Ridges, escarpments, mountains on non-granitic Palaeozoic rocks (Ararat, Colbinabbin, Pyrenees, Tarrangower, Big Hill, Mt Macedon)
2.1.2 Hills, valley slopes and plains on non-granitic Palaeozoic rocks (Daylesford, Maryborough, Bendigo)

2.1.4 Hills, valley slopes and plains on plutonic Palaeozoic rocks (Pittong, Harcourt, Amphitheatre, Victoria Valley)
2.1.5 Plateaux and rises of residual Cainozoic landscapes (Dereel, Meredith, White Hills, Trentham)
2.1.6 Eruption points and volcanic plains (Creswick - Ballarat plains, Mt Franklin, Mt Blackwood, Metcalfe)
2.1.7 Terraces and floodplains (Upper Loddon, Upper Woady Yallock Creek, Pomonal - Moyston area, Crowlands, Avoca, Newstead)
The dissected uplands are characterised by a variety of interwoven landforms preserved by substantial uplift during the Palaeogene (Carey & Hughes 2002) and late Neogene (Taylor et al. 1996). Undulating hills and broad valleys characterise the Palaeozoic sedimentary rocks and granitic plutons. Remnants of an early Cainozoic palaeoplain occur as caps of Palaeogene gravels sporadically distributed at various elevations, such as those around Meredith. A remnant of the sands deposited during the Pliocene marine regression fringes the southern Palaeozoic rocks as a dissected tableland around Illabarook and Rokewood. During the Plio-Pleistocene, volcanic eruptions filled the broad valleys to form elongate basalt plains and a variety of other volcanic landforms. The prominent volcanic cones of Mount Buninyong (745 m), Mount Warrenheip (741 m) and Tipperary Hill (743 m) are now the highest elevations in the Corangamite CMA region. |
