Aplicación de la microscopía electrónica de barrido al análisis de sedimentos recientes en ambientes fríos

Abstract

In this article we ..:vil! explain the results of the application of the Scanning Electron Microscope to the study ofthe origin and evolution ofthe sediments corresponding to a cold environment, which are placed in the southern slopes of the Pyrenees, in the Gállego-Ara watershed. The samples selected belong to modern alluvial deposits, morainic deposits and a complex recent formatíon, with a hypothetical glacial or lacustrine origino
