Abstract

Active karst landforms (poljes, dolines, sinkholes, caves and rillenkarren) and hydration and weathering phenomena on anhydrite and limestone are described from the Tripolitanian pre-desert. Rainfall in the study area is considerably less than the 250–300 mm a−1 previously suggested as the minimum precipitation threshold for the development of karst landforms. These findings suggest that the presence of karst land-forms in an arid region cannot necessarily be taken as evidence for higher precipitation levels in the past.
