Special issue. Geomorphic response of mediterranean and arid areas to climate change
Salt caves respond rapidly to environmental changes. Direct measurement and C 14 dating show that complex cross-sections may develop in a few hundred years. Two basic forms are discussed : 1) ingrowing vadose canyons where changing width may
correspond to changing discharge; 2) wide low passages with flat ceilings, developed by upward dissolution, which may indicate rising base level. Some cross-sections are deformed by Holocene tectonics.
