Abstract

The cavernous forms have been developed in a great variety of rocks : gneisses, granitoids, amphibolites and breccias. The weathering is physico-chemical. The weathering material usually contains some clay minerals. The weathering processes in ceilings and walls are flaking and granular disintegration. They seem mostly to be caused by water freezing in micro-fractures combined with chemical weathering. The ventilation of tafoni voids regulates the pace of subsequent weathering
