Postglacial Landscape Changes and Cryogenic Processes in the Picos de Europa (Northern Spain) Reconstructed from Geomorphological Mapping and Microstructures on Quartz Grains
Abstract A 5.4 m long sediment core was collected from Belbín, a karstic depression dammed by a moraine in a mid‐altitude environment in the Western Massif of the Picos de Europa of the Cantabrian Mountains, northern Spain. 14 C AMS dating of the basal sediments in the core suggests that the maximum...
