Although there is a relatively consistent flux of salt from low hills and rises with preserved Cenozoic gravels and duricrusts
on the crests, these features are often isolated and localised.
For instance, scarp recession may succeed a sequence dominated by slope lowering in weak strata if a resistant stratum is uncovered or if a potential duricrust
develops in a weathered mantle.
2000) of catenary sequences of soil profiles describe upper slopes with typical lateritic soil profiles (Oxisols or Ferralsols) that have originated from the alteration of lateritic duricrusts
developed from underlying sedimentary rocks (sandstones, mudstones, and siltstones from the Mesozoic Upper Bauru Group).
Duricrusts are among the most common surface phenomena known that affected ancient and modern landscapes.
Continentally formed duricrusts have frequently been reported from Spain.
In analogy to calcrete duricrusts, the term palycrete can be accepted for this duricrust.
Similarly, the widely occurring Fe nodules and duricrusts in coastal eastern Australia have been described as eroded remnants of laterite duricrusts (e.
