Abstract
El sistema endokárstico de Seso (Boltaña, Huesca), localizado en el sector
central surpirenaico, presenta una espeleogénesis singular. La excavación
mecánica en condiciones vadosas de material margoso fácilmente erosionable
(procesos de piping) constituye el principal mecanismo espeleogenético.
La disposición espacial del sistema endokárstico respecto a las terrazas
datadas del río Ara permite situar la formación de la cavidad en el
Pleistoceno superior, probablemente coincidiendo con fases húmedas del
MIS 4
The Seso Cave system (Boltaña, Huesca province) in the Southcentral Pyrenees presents a singular speleogenesis. Vadose mechanical entrenchment of highly erosive and dispersive marls (piping processes) is the main espeleogenetic mechanism. Geometric relationship between the endokarstic system and a terrace of the Ara River chronologically controlled allows dating the cave formation in the Upper Pleistocene, probably during stages of the MIS 4 with high water availability
