Caves with Pissarres lithology

Slate is a fine-grained, practically insoluble metamorphic rock: the cavities found in it are not the result of chemical dissolution but of fractures and mechanical processes, such as landslips or openings along foliation planes. These are rare cavities in the catalog, and each tends to have its own local geological explanation rather than a repeatable pattern.

5 cavitats with lithology Pissarres are part of the catalogue. Most are found in Vielha e Mijaran, Arres and Queralbs. VETA NEGRA, COVA DE LA, amb 28 m de recorregut.

La litologia Pissarres és una roca metamòrfica de gra fi i molt poc soluble, on les cavitats són rares i solen respondre a fractures o processos mecànics més que a dissolució.
