abstract = {The results of research on stratigraphy of slope covers in the southern part of the Ojców Plateau are presented in the paper. A slope cover is understood as the sediment overlying the Mesozoic basement. These are as follows: scree, glacigenic and periglacial deposits. A special attention is put on periglacial slope covers represented by loess, weathered debris, and the deposits originated due to redeposition of loess and scree along the slope. 50 sites has been examined. Detailed sedimentological logging was fulfilled, the a axis orientation of clasts as well as the azimuths of dip lamination were measures. Grain size of deposits, clay mineral content, and morphology of the limestone clast surfaces were examined. The content of CaCO 3 , Fe 2 O 3 and C org were analysed for fine-grained deposits and for the diamicton matrix. The presence of the Pleistocene fossil soils has been documented; soil lessive - fig 2, and pseudo-gleyed soil - fig. 6. The analysis of the chemical weathering rate indicated the presence of a few deposit generations, originated in result of slope redeposition (scree deposit; solifluctite; mass flows and deluvial deposit - tab. 1). The succession of the fossil soils and the slope covers seem to be a plausible background for the stratigraphical correlation of the periglacial covers. The published loess profiles from the Cracow area and from the Nietoperzowa Cave are compared to the slope deposits; the results are discussed. Loess stratigraphy is according to classification by Jersak et al. [1992]. Presented research shows that the karstic weathered debris and glacigenic deposits are residua in this area. Karstic weathered debris comes from the late Pliocene/early Pleistocene. Glacigenic residuum is dated to Sanian Glaciation. Periglacial slope covers represent the period of time from the decay of the Wartanian Glaciation to the decay of the Vistulian Glaciation (fig. 8). During the Pleistocene on the slope of the Ojców Plateau denudation rate was higher than accumulation rate. In result the deposits correlated with the Older Upper Loess, the Nietulisko Horizon and the Younger Loess IIa are noted as the residua only. The deposits correlated with the Komorniki Horizon are noted only locally too. The slopes are dominated by the Younger Loess horizon as well as by the scree deposits originated simultaneously. The last phase of the slope processes development took place in the decay of the Vistulian; a distinct erosion of the Younger Loess IIb and accumulation of loess deluvia of considerable thickness are dated to that phase.},
