【 摘 要 】

The fluvial terraces of the Cares river: sedimentological and chronological contributions (Picos de Europa, Asturias) . An analysis of the system of fluvial terraces in the Cares River and its tributaries in Arenas de Cabrales is presented. A total of nine terrace levels were identified with heights of +90 m, +60 m, +60 m, +42-50 m, +20-22 m, +14-17 m, +12 m, +8-10 m, +6-7 m and +5 m above the actual river bed. The sedimentological features of alluvial deposits and their relations with others landforms (stratified debris and alluvial cones) have been studied, outlining a chronology for two terrace levels based in absolute datings of14 C, as well as an incision rate of Cares river of 0.24 mm/year during the last 37.000 years.
