Granite Caves in Catalonia

Granite is a plutonic igneous rock, formed by slow crystallization at depth, and practically insoluble in water. That’s why cavities cataloged in granite are scarce: when one does appear, it tends to result from differential erosion between blocks or the opening of cooling joints, not from a karst process like the one in limestone areas.

There are 129 cavitats (126 coves i 3 avencs) catalogued with Granite lithology, mostly in Tossa de Mar, Palafrugell and Sant Feliu de Guíxols. Cova Des Bergantí, amb 224 m de recorregut.

The surveyed length of the caves with this data ranges from 3 to 224 metres. The depth ranges from 1 to 27 metres. Each entry includes exact location, coordinates and, where available, photographs and survey maps, with a downloadable GPX track. The whole list on this page can also be exported as CSV or JSON.

La litologia Granits és una roca ígnia plutònica pràcticament insoluble, on les cavitats catalogades són escasses i solen respondre a processos d'erosió diferencial.
