Resumen de Identificación de eventos de inundación en el interior de cavidades kársticas: Cueva Fría (Asturias – NW España)
Saúl González Lemos, Heather Stoll
Fluvial records may be well preserved in subterranean karst drainage networks and fluvial deposits cemented in speleothems may provide good chronology of past flood events. In several karst systems in Asturias (NW. Spain), moments of extreme precipitation events produce deposits from flood events in the bed and walls of caves which we propose are also recorded in the calcium carbonate stalagmites growing in the cave. The interpretation of the detrital layers and the dating of the stalagmites can provide a chronology, so that the abundance of fluvial material in the stalagmites can reveal periods of enhanced vs. reduced flooding in the cave over the past several thousand years (Holocene).
