Sinkholes occur throughout the Campania territory both in soils and in rocks. Sinkholes in strongly karstified carbonate massifs are described by means of geological and geomorphological analyses. The interpretation of air photographs
and topographic maps allowed the recognition of 77 sinkholes which were catalogued on the basis of their main morphometric features (depth, axial length, volumes, etc.) and geological (lithological, structural) and hydrogeological context. These data suggest high
In this paper, after a short geologic outline of the Naica area, the mechanisms responsible for the genesis and the evolutionary steps of the Naica cave are discussed in detail mainly on the basis of the chemical deposits hosted inside the cavities
