Propuesta de un modelo cronológico para las terrazas de los ríos de la vertiente cantábrica

Abstract

A new fluvial terraces chronology Is proposed for the rivers in northern Cantabrian Range. Six terrace levels were identified and mapped. These have average heights of 2,5; 10; 15; 20; 35; and 63 m above river level. Four older surfaces were identified at 125, 250, 600 and 800 m above these terraces. The new ages place the Pleistocene terraces at 35 m above the fluvial channel. A discussion ab o u t the accuracy o f the ages is presented
