Abstract

Weathering features are described from a meteorologically arid area in southern Tunisia. The active development of a complex microkarst and associated salt weathering are combining to destroy linear karstic features such as rillenkarren, widespread case-hardening and in places patches of iron- and manganese-rich rock varnishes. The complexity of active and inherited weathering features belies the perceived simplicity and lack of weathering opportunities associated with aridity. Instead it focuses on the need to consider the nature of microclimatic conditions at the rock/air interface especially when seeking to define desert weathering environments
