Abstract
Results from glacial geomorphology analysis of Fuentes Carrionas Massif are presented here. Based on the interpretation of glacial landforms, glacial evolution since the Last Glacial Maximum until total Pleistocene deglaciation is described. Four different glacial equilibrium phases are identified, the last one divided into two pulsations. Glaciers tongues reached 15 km. long and occupied valleys down to 1250 m.a.s.l., and subsequently retreated to small glaciers located at cirques above 2000 m.a.s.l. Deglaciation process took place between 36 ka BP and 11 ka BP. Finally a palaeoenvironmental reconstruction is proposed, based on ELA (Equilibrium Line Altitude) rise, in which temperatures ranged between 9⁰C and 10⁰C lower than present ones, depending on a
precipitations variation between 30% higher and 20% lower than current ones.
