Pogórze Śląskie - Opis:
- The paper presents the succession of Sanian Glaciation sediments recognized in the Swiętoszówka site, Southern part of the Silesian Foothills (Bielsko division). The following deposits were found: a unit ofgravels deposi- ted in a system offoremountain alluvialfans, a unit of silts deposited in a glaciomarginal dammed lake, and a glacial till. Glaciogenic deposits are covered with loess-like deposits. The development of the glaciomarginal zone was influ- enced mainly by the pattern ofbasement relief. In the northern part of the foothill, in the northward-oriented valleys, glacially dammed lakes were mainlyformed. During transgression, waterfrom these reservoirs was pushed in front of the ice-sheet margin towards the southern part of the low-relieffoothill. The individual lakes probably merged there into one larger glaciomarginal lake. It was characterized by low-energy conditions and deposition mainly from suspension. Sedimentation style in the lake changed over time and was dependent on the size and shape of the lake and its position in relation to the ice-sheet margin, which determined thewidth and distribution ofzones of sediment supply and the dynamics ofdepositional processes in the lake.
