Resumen

Géomorphologie mapping and structural data provide the preliminary results of the géomorphologie features of the Pindal Cave and surrounding area, described in this work. The landscape results from fluvial, mass wasting, karstic and marine processes, with the outstanding presence of two erosion marine surfaces called "Rasas": Pimiango (125-170 m) and Pindal (50-64 m). The origin of the Cave, developed in the karstic massif reaching its highest level in Pindal Rasa, is mainly controlled by two fractures trending E-W. The géomorphologie evolution of the Cave is due to 7/ block collapse from the roof related to three joint systems; 21 the episodic infilling by detrital sediment coming from denudation of Pimiango Rasa Range and 3/ the chemical precipitation of speleotheme overlying both alluvial and collapse deposits. The present dynamics of the Cave is controlled by vadose conditions and collapse processes and sporadic flooding of channel inside the cave. A lower active level is inferred from scarps development in deposits over the floor cave
