Pleistocene glacial fluctuations and chronology in the Pas Mountains (Cantabrian Mountains)

Abstract:

This paper analyses the glacial evolution of the Pas Mountains, in the Eastern Cantabrian Mountains, the glacial landforms and deposits by geomorphological mapping, electric and seismic surveys, and dating intramorainic peat bog and till deposits. The external morainic complex (S-I) shows a glacial extension maximum before29.150-28.570 cal a BP. A second glacial advance and equilibrium (S-II) have been studied in the entire massif, with glaciers reaching similar positions to the previous phase. Finally, two phases (S-III and S-IV) with very small glaciers developed in the cirque. The last equilibrium glacial phase has been attributed to Late Pleistocene cold phases, previous to Tardiglacial ones. Dating in the Pas Mountains are in agreement with previous dating in the Cantabrian Range and bears out the existence of a glacial maximum, previous to the European LGM.
