Geology
Paleozoic sediments (sandstones, mudstones and shales).
Landform
Rolling low hills.
Soils
The surface soils on the slopes and crests are brownish grey or grey very fine sandy loams to silty clay loams with a bleached zone of similar texture at about 10 cm. Yellow-brown mottled with light grey medium clays occur at about 40 to 60 cm often with ironstone concretions above the clay. Variations in colour and texture of the surface soil, as well as the depth to rock occur with landscape position. Rock generally occurs at between 1 to 2 m.
