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).
