New geological and geomorphological investigations carried out in different parts of the Fore-Carpathian region of the Dnister River basin gave an opportunity to distinguish at least four separate different-age levels (terraces) within the Loyeva level (sixth terrace): Torhanovychi, Dubrivka, Susidovychi and Biskovychi.In the Solonske section the alluvial and cover loess-soil sediments from the Lower to Upper Pleistocene of the total thickness of about 30 m are revealed. Loess-soil series of the investigated section represents a number of loess and palaeosol horizons from modern soil (MIS 1), which is developed on the Horokhiv fossil soil complex (MIS 5), to the soil with spot-medallions (MIS 17–19). The last one was formed above the permafrost and obviously can be correlated with one of the soils of fossil soil complex of Zahvizdia type. A very thick (almost 10-meter) stratum of deposits that, apparently, have a limnic origin is underlying this soil. Alluvial deposits, which are directly under the limnic stratum, are composed of the channel and flood-plain facies and represent one of the identified separate levels of the Loyeva level (the sixth over-floodplain terrace of the Dnister River).In Solonske section two levels of the development of palaeocryogenic structures like spot-medallions are revealed (above the Lutsk fossil soil (MIS 9) and over one of the soils of fossil soil complex of Zahvizdia type).Undoubtedly, under the conditions of the proper further investigations of the section, Solonske can become a key point for Pleistocene not only for Fore-Carpathians. It will be important in determining the time of the formation of different-age levels of the Loyeva level.Key words: loess-soil series, alluvium, terrace, palaeocryogenesis, spot-medallions, Pleistocene, Loyeva level, Dnister, Fore-Carpathians.
