Abstract

Karst caves are one of the most prominent features of the Picos de Europa National Park, in which morethan 470 km length of cave passages discovered by speleologists, are still poorly known from the scientificpoint of view. This project has contributed to enhance the value of geoheritage linked to endokarst, with thegeomorphological and geochronological study of two karst cavities, more than 2 km long («Torca la Texa»and «El Frailín de Camplengu»). The methodology of work combines speleological methods (topographic,morphometric and 3D models of the cavities) and geological methods (geomorphological a geological mapping, geochronology, structural analysis). The results of the project show that: 1) caves are formed by phreatic and epiphreatic passages, vadose shafts and canyons, and gravity enlarged passaged, in which fluviokarst,gravity and chemical precipitation forms appear; 2) the development of the cavities is controlled by fluvialnetwork incision, glacial action, climate change and the geological bedrock (structure and lithology); 3)the evolution model of the caves includes six phases, and the origin of the caves is prior to 350 ka (MiddlePleistocene). The information of the project provides a robust base of scientific knowledge that has beentransferred to the OAPN, and also to the scientific community, the Picos de Europa National Park and to different social sectors and media, with the elaboration of a doctoral thesis, scientific publications, conferences,appearance in social media and design of educational videos. Therefore, we have reached the double aim ofresearch development and transfer of knowledge to the Administration and Society.
