El hidrolacolito de las Calderuelas (Parque Nacional de la Sierra de Guadarrama), una morfología periglaciar singular

Abstract

This research describes the finding of a hydro-laccolith in the Sierra de Guadarrama (Central System). The study, based on the combination of Digital Terrain Models (DTM) and geoelectrical data, allowed the characterization of the surface morphology and internal structure. The results allow establishing the genesis of this periglacial-related structure and the role played by slope processes in its evolution. Freeze-thawing cycles and hydrogeological conditions are responsible factors that control its evolution over time. Such type of structures show an extraordinary environmental sensitivity, thus their monitoring is of great interest to guarantee their further preservation.
