ENGINEERING-GEOLOGICAL CHARACTERISTIC OF THE ROCKS OF THE LOESS-SOIL SERIES OF THE KEY SECTION PIDVOLOCHYSK (PODOLIAN UPLAND)
Journal Title: Вісник Львівського університету. Серія географічна - Year 2016, Vol 50, Issue
Abstract
Key section Pidvolochysk is located in the quarry of the currently inactive brick factory. It represents the Upper and Middle Pleistocene loess-soil series as well as some fossil paleocryogenic forms of the Khmelnytsky Plateau of the Podolian Upland. The ice wedge casts of the Final Pleistocene (Krasyliv) palaeocryogenic stage are presented here especially intensely. One of them is studied on the engineering-geological aspect. In particular, it has been defined, that the loess filler of ice wedge cast, in contradistinction to loesses that contain it, is loose and subsiding. This is of great importance for the engineering-geological evaluation of the properties of loess-soil strata. Key section Pidvolochysk is well stratified. Two Upper Pleistocene loess horizons (MIS 2, 4) and the upper horizon of Middle Pleistocene loesses (MIS 6) are disclosed here. Besides loess horizons, Dubno fossil soil (MIS 3) and Horokhiv fossil soil complex (MIS 5), as well as delluvial-solifluctional stratum above Dubno, are developed here. The engineering-geological properties of the loess and palaeosol horizons, including their subsidence, have been studied in detail. Individual characteristics of distinct stratigraphic horizons are given. It can be used during the engineering-geological research in the areas of distribution of Pleistocene loess-soil series.
