W artykule przedstawiono analizę litofacjalną osadów budujących niszę niwalną, wykształconą na południowym zboczu Pradoliny Toruńsko-Eberswaldziej i dokonano ich interpretacji genetycznej. Cechy morfometryczne formy (długość, szerokość, spadki zboczy) obok cech litofacjalnych stanowiły podstawę do zaklasyfikowania badanej niszy do grupy nisz niwalnych. Ponadto wykazano, że procesy soliflukcji i spłukiwania uznać można za dominujące w rozwoju analizowanej formy.

This paper show the result of lithofacial analysis of deposits in nivation niche that was undertaken in the south edge of the Toruń-Eberswalde ice-marginal valley. The structural and textural parameters of the distinguished deposits were examined and interpretation if their genesis was made. The morphometric features of the investigated form (its length, width, gradient of slopes) and the lithofacial characteristic were the basis for its classification as a nivation niche. Besides, it was shown that solifluction and rillwash were the most important processes during its formation.
The outcropin Dziembowo, located in the edge of Notec Pradolina allows to led the detailed lithofacial analysis. As a result of it two till layers were recognized, that are divided by deposits of catastrophic glaciofluvial rising. There were recognized textural, structural features and petrographic composition of glacial tills.
The outcropin Wolsko Dolne is located in one of the hills ofWyrzysk Oscillacion end moraines. There were recognized four complexes of glacial and glaciofluvial deposits. Glacial tills were identified with help of detailed lithofacial analisys. There were recognized textural, structural features and petrographic composition of glacial tills
The investigated area is located along the Noteć Middle Valley and is situated on the border of several physical-geographical and geomorphologic units. There are according to Krygowski (2000): the Noteć Middle Valley, the Gwda Valley, the Wałcz Lake District, the Kraina Lake District, the Chodzież Lake District. Varied geological structure and the relief of the area. The expression of dynamic activity of the last Scandinavian ice sheet are impressive ladforms like end moraine hills of the Chodzież subphase, the Wyrzysk oscillation, glacial gully, outwash levels.
The outcrop in Krostkowo, located in the western part of Dębowa Góra (Oak Mountain) Complex - the highest point of Wyrzysk Oscillacion end moraines. There were recognized two till layers, with glacitectonic disturbances, divided outwash deposits with glacial tills incorporations. There were recognized textural, structural features and petrographic composition of glacial tills.
