First results of a study on hypogenic caves in Sicily are presented. Inactive water-table sulphuric acid caves and 3D mazecaves linked to rising of thermal waters rich in H2S were recognized. Cave patterns are guided by structural planes, mediumand small scale morphological features are due mainly to condensation-corrosion processes. Calcite and gypsum representthe most common cave minerals. Different types of phosphates linked to the presence of large bat guano deposits wereanalyzed.
