Abstract
Description and detailed engineering-geological characteristic of rocks of the loess-soil series of one of the most complete loess section of Podolian Upland were given. Sharovechka key section represents the main loess and palaeosol horizons of Lower, Middle and Upper Pleistocene. There is total thickness of loess-soil series approximately is 25 meters in this section. Horokhiv and Korshiv fossil soil complexes, Lutsk and Sokal fossil soils, and lower horizon of Lower Pleistocene loesses can be key horizons for all territory of Volhyn-Podillia. The monoliths were taken from all stratigraphic horizons of this section with the purpose of investigation of engineering-geological features including subsidence. The analysis of the distribution of composition and features indexes in loess and palaeosol succession demonstrates a significant difference between their certain horizons caused by peculiarities of paleogeographic conditions of their formation and diagenetic transformation. It was also deduced that the degree of contrast of parameters of composition and features of loess and palaeosol horizons in comparison with key loess sections of Volhynian Upland was much lower. Probably this was caused by the higher total content of clay in soils of certain stratigraphic horizons and by the direct overlay of different types of fossil soils at each other.
