MM439

Site: MM439	Land Unit: Beaufort Non-Marine Sandstone
*Aust. Soil Class.:* Bleached-Mottled, ?, Brown CHROMOSOL (confidence level 4)

General Land Unit Description:
This unit is found in association with the Beaufort Marine Sandstone land unit around Beaufort. The major landforms in this land unit are undulating rises and rolling low hills. The major soil type found on the slopes of the rises is a strong texture contrast soil (Chromosol) with a bleached A2 horizon and a mottled subsoil. The steeper slopes and crests tend to have shallower gradational soils (Rudosols, Dermosols). Some redder soils (Dermosols) can occur on the better drained slopes.

Site Description:

Geology: Cambrian non-marine sandstone	Landform pattern: Undulating rises
Position in landscape: Upper slope	Internal drainage: Well drained
