Abstract
El capítulo "The Glaciers in Western Galicia" analiza la formación y evolución de los glaciares en montañas de baja altitud en Galicia occidental, como la Serra do Xistral, los Montes do Cebreiro y Oribio, y la Serra Faro de Avión. Durante el Pleistoceno, estas áreas albergaron glaciares a altitudes excepcionalmente bajas, impulsados por climas fríos y húmedos propios del entorno marítimo atlántico. Se identificaron 42 paleoglaciares, con características como circos glaciares, valles en forma de U y morrenas asociadas. La cronología muestra un máximo glaciar local (lLGM) hace más de 35,000 años, seguido por una fase más seca y fría durante el gLGM (26.5-19 ka), y una deglaciación posterior desde hace 19,000 años. Durante el Holoceno, las montañas permanecieron libres de hielo, aunque nevadas estacionales significativas se registraron en la Pequeña Edad de Hielo (siglos XVIII-XIX). Estos glaciares destacan en el contexto europeo por su formación en condiciones climáticas únicas, dejando una impronta geomorfológica relevante y un registro paleoclimático excepcional.
Glaciers in very low mountains near the coast, with peaks of c. 950 m, have been described in Northwestern Iberia. The high precipitation in these mountains facilitated the formation of glaciers during the Pleistocene. In the first phase, the important contribution of snow determined the existence of small ice fields in these mountains; later, very intense cooling facilitated their transformation into cold-based glaciers, particularly the wedge-shaped ones. The study of these glacial landforms is of great interest to better understand the palaeoclimatic conditions that prevailed in the Atlantic regions of the Iberian Peninsula during the Late Pleistocene.
