Abstract

This study deals with analysis of instability phenomena in the Upper Miocene to Pleistocene deposits of the evaporite karst in the Crotone Basin (Calabria, southern Italy). A type of instability is represented by sinkholes, a very common karst landform in evaporite rocks. The effects from gravitational and erosional processes are described in the article also through direct observations within the underground system, which pattern is controlled by a combination of tectonics and breakdown mechanisms. The low resistance of evaporites, locally increased by prevailing clays in the stratigraphy, determines high frequency of fallen blocks. The comparison between the landforms and deposits observed at the surface and underground pointed out to the difficulty in directly linking what is observed at the ground with the processes acting within the karst system. This has obvious consequences in terms of civil protection
