Granite caves in the north-east of the Iberian Peninsula:Artificial hypogea versus tafoni

摘要

Granite caves in the north-east of the Iberian Peninsula: Artificial hypogea ver-sus tafoni. The origin of eight supposedly artificial caves in granite rocks located in the north-east of the Iberian Peninsula is revised in this work. Although human features are present in four of the caves, they have little morphological significance, and therefore their attribution is re-evaluated on the basis of geomorphological analysis and tafoni genesis theories. In fact, these cavities are tafoni developed in bornhardts, castle koppjes, tors and corestones.
