Na podstawie badań terenowych przeprowadzonych po wschodniej stronie rynny jeziora Jasień oraz z wykorzystaniem
literatury z zakresu paleogeografii, autor dokonał rekonstrukcji przebiegu procesów stokowych, które zaszły w
późnym vistulianie i holocenie. Badania pozwoliły wyróżnić etapy kształtowania się dolinek erozyjno-denudacyjnych i powstawania
osadów stokowych. Wykazały one również wpływ działalności człowieka na rozwój wymienionych zjawisk i pozwoliły
umieścić je w ramach czasowych.
The Jasień lake trough is situated in northern Poland, in the eastern part of West Pomeranian Lakeland. Main geomorphic features of the area developed during the advance of the Bytów ice lobe and its subsequent decay, ca. 16,000 years ago. Research focused on the evolution of erosion-denudation landforms and characteristics of slope deposits was based on detailed field work, which involved excavation of numerous test pits within dry valleys dissecting the eastern slopes of the Jasień lake trough. The onset of valley morphogenesis can be dated for the period immediately preceding the Oldest Dryas. Seasonal concentrated runoff caused initial dissection of the topographic surface sloping towards the lake. Later on, probably in the Oldest Dryas, solifluction and surface wash began to re-shape valley sides, which have been later transformed by different processes and yielded different types of sediments. During warmer periods, particularly at their waxing stages, valley floors were subject to dissection, as testified by pavement surfaces, and stored sediments moved down the valley. Slope deposits formed mainly during cooler stages of the Vistulian and at the turn of the Holocene. Lithologically, they represent stony-gravel horizons related to solifluction and sandy deluvial series. The period between the Preboreal and Subatlantic witnessed little geomorphic activity and is recorded in well developed palaeosols. Slope activity resumed in the early Middle Ages, under the influence of people. - Źródło:
