Description :
The aims of this paper are to contribute to the understanding of the origin and role of case hardening through an examination of the physical, chemical and biological characteristics of case hardening from 4 inselberg sites near Wadi Rum, Jordan. The AA. test 2 specific hypotheses : firstly, that case hardening is indeed occurring on column surfaces and contributing to the development of column and niche relief here; secondly that endolithic biofilms play a role in the development of these case-hardened surfaces.
