Opis:
Slope covers investigation reveal possibilities of extensive palaeoclimatic/stratigraphic reconstructions. This paper approaches the problem by presenting the results of sedimentological analyses upon periglacial slope deposits in the southern part of the Ojców Upland. Periglacial slope covers (loess, weathered debris, sediments deposited in result of slope proceses), originated during and after the youngest loess accumulation (in conditions of permafrost thawing), have been the object of research. Both climatic and morphologic conditions of slope covers genesis are analysed in detail. Climate reconstruction is based on the analyses of slope deposits successions examined underneath the rock walls, on the steep slopes and gentle slopes, respectively. Presented research proved that slope cover analysis may be a basis for palaeoclimatic interpretations, however it must have been preceded by studies of morphological conditions of slope material redeposition. The same climate changes may have resulted in different succession of slope deposits, depending on local slope relief.

Opis:
In this paper an attempt is made to identify the depositional environment of glacigenic deposits from the central part of the Holy Cross Mountains (Kielce-Łagów Valley). In this area, the primary glacial relief is very poorly visible, mainly due to its modification by subsequent denudation processes. The study is based on detailed sedimentological (macro- and microstructural) analysis of the deposits. The bottom part of the deposits consists of gravelly and sandy facies. They are overlain by diamicton facies, with a small proportion of sandy facies. Clayey/silty facies occur in minor quantities. The investigations indicate that these deposits represent an ice-marginal environment. Local stagnation of the ice sheet lobe was controlled by the geological structure of bedrock (karstified and faulted limestones) and the features of a fossil valley. The ice-marginal depositional environment is indicated by the predominance of sediment-gravity flow deposits, a low proportion of sorted deposits, as well as the interfingering/alternating of mass flow deposits and waterlain deposits. Deformation occurring in the deposits is of gravitational origin. They also show traces of periglacial processes. The deposits constituted an ice-marginal moraine (dry end moraine with limited topographic expression). Micromorphological analyses provided data for genetic identification of the deposits, and allowed the inference about rheology of deposition and deformation processes. However, in some cases, they did not allow unequivocal genetic classification of the deposits. The results of presented investigations confirm the opinion that detailed and complete explanation of deposit origin requires both micromorphological analyses and macroscopic field sedimentological and structural studies.

Opis:
The identification of depositional conditions and stratigraphical position of glacigenic deposits in the Napęków area is important for the genetic and stratigraphical interpretation of Quaternary deposits in the central part of the Holy Cross Mountains, as well as for a revision of the course and extent of Middle Polish (Saalian) glaciations. These deposits comprise a series of diamictons which occur between sandy-gravelly deposits. Based on results of macro- and microscopic sedimentological investigations, analysis of heavy mineral composition, roundness and frosting of quartz grains, as well as OSL dating, this complex must have formed during the Odranian Glaciation (Drenthe, Saalian, MIS 6). Sandy-gravelly deposits are of fluvioglacial and melt-out origin. Diamictons represent subglacial traction till. Their facies diversity is a result of variations in time and space, complex processes of deposition and deformation, responsible for their formation at the base of the active ice sheet. This glacigenic depositional complex was transformed by erosion-denudation and aeolian processes in a periglacial environment during the Vistulian (Weichselian, MIS 5d-2).
