1.   In presently arid central Australia, for instance, deep weathering profiles are to be found which have clearly been inherited from a previously more humid climatic regime.

2.   The physical characteristics of weathering profiles depend upon the rock type and its structural properties and mineralogy as well as the intensity and nature of the chemical weathering processes.

3.   A number of geomorphic studies have focused on weathering profiles developed on granite under humid tropical and subtropical climates.

4.   Vertical differentiation in mineralogy in weathering profiles may also reflect the stage-by-stage alteration of primary rock minerals.

5.   We always have to be aware of the kinetics of weathering reactions when looking at the mineralogical composition of weathering profiles.
