Abstract

[automatically translated] The Cave of the characters is located in western Sicily, near Mount Magaggiaro, S of the town of Montevago (AG). In the area there are hot springs, characterized by chlorine-alkaline-earth sulphate water with about 40 ° C temperature and pH 7. The Cave of Characters, known since the early 1900s and also known for archaeological finds, was never It has been detected and studied in detail. The cavity is spread mainly in limestones of the training platform Inici (Jurassic inf.) And limestone escarpment and the pelagic Buccheri formation (Jurassic Inf.-sup.). This is a sub-horizontal cavity that presents a development of about 1.7 km, a height difference of 15 m and ascending descending of 32 m. The ducts and labyrinthine pattern is strongly influenced by the geological structure; there are no real wells, but only fractures that shrink in depth; the ascending branches are characterized by domes which interpenetrate upwards. Among other morphologies are recognized holes from dripping, to condensazionecorrosione channels, condensation spheres, feeder mouths, pillars and partitions. Inside the cavity it is also present a colony of bats and various deposits of minerals still under study. The analysis of large- and medium-scale morphology and the presence of thermal waters in the area seem to indicate that the genesis of this cavity is linked to ipogenici processes.
