24 Brown, red and black gradational or loam (earth) soils and red clays on Quaternary, Neogene and Palaeogene limestone
| These soils mainly occur in the south-west of the CMA where dissection of the landscape has exposed limestone deposits (Port Campbell Limestone). This area has a higher rainfall than the basalt plains to the north and north-east. There are minor occurrences of limestone members (Maude Formation) on the drier Bellarine Peninsula. Many of these soils have shallow to moderate depths (30–80 cm), directly over limestone or calcareous deposits, and consist of dark (black, brown or red) strongly structured clay loams with few limestone fragments. The deeper soils have clay subsoils that are vertic and occasionally clayey throughout. Notable characteristics are the gradational nature of the soils with strong fine structure and often shallow depth to rock. |  |
