PVI 4

Site: PVI 4Land Unit: Monivae Basalt
Aust. Soil Class.: Endocalcareous, Epipedal, Grey VERTOSOL (non-gravelly surface) (confidence level 1)

Soil pit PVI 4 landscapeGeneral Land Unit Description:
The level to gently undulating basalt plains between Branxholm and Glenthompson consist of an association of Vertic or Ferric Brown Chromosols and Ferric Brown Sodosols. The Chromosols typically occur on the upper slopes and crests of very slight rises that may have scattered surface boulders, and Sodosols on the lower slopes and depressions. Sodosols or Vertosols, occasionally with a sporadic bleached subsurface horizon, are usually found in open depressions or drainage lines.

Site Description:
Geology: Quaternary basaltLandform pattern: Level to gently undulating plain
Position in landscape: Low lying area below riseInternal drainage: Moderately well drained
