ABSTRACT

On the basis of studies of the Pleistocene stratigraphy of the Holy Cross Mountains and their surroundings, six till units, deposited by the Scandinavian ice sheets, can be distinguished. These tills are occasionally separated by interglacial sediments. During the Nidanian Glaciation, the Scandinavian ice sheet covered the northern slopes of the main ranges in the Holy Cross Mountains to an altitude of about 300-350 m above sea level. Palaeomagnetic investigations at Kozi Grzbiet have demonstrated that the Matuyama/Brunhes magnetic reversal occurred during the Nidanian Glaciation in the Holy Cross Mountains. In the Holy Cross Mountains and further to the south, the till immediately underlies the present land surface. The Odranian Glaciation ice sheet formed many end moraine features, particularly at the northern and western margins of the Holy Cross Mountains. During the Eemian Stage organic sediments were deposited. They are known from the sites such as Bedlno and Slawno in the western and northern foreland of the Holy Cross Mountains.
