Aproximació a l'estudi sedimentològic i paleoclimàtic d'un assentament prehistòric: la Cova del Parco (Alòs de Balaguer, La Noguera)

The cave of Parco is found in the pre-Pyrenean massif of Montsec, in the northern interior region of Catalonia, an area dominated by a present day arid or semiarid climate. The deposit, opened up in sections, is made up of a single gallery cave which communicates to the west with a shelter. In this study a sedimentological analysis of one stratum with a thickness of 2.38 m. consisting of sterile strata of the end of the Upper Paleolithic, Epipaleolithic and Neolithic periods is described. The fifteen layers studied are grouped into four stratigraphic and sedimentological units. Finally the sedimentary, paleogeographical and paleoclimatic evolution of the area is calculated. For the latter six regional climatic pulses are proposed ranging from the end of Upper Pleistocene to Atlantic
