The pedosphere in the Gina River catchment shows following characteristics:

  • There is an area-wide pattern of soil sediments covering the saprolite with a sharp boundary.
  • This indicates that most soils in the Gina River catchment did not develop in situ.
  • In-situ soils occur only locally (e.g., Nitisols or Fluvisols).
  • In most locations there are also no diagnostic horizons stating soil types.

Clay minerals (e.g., Halloysite, Kaolinite) are the most important weathering products (Beck et al. 2004).
