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. Key words: loess-soil series, key section, Pleistocene, palaeocryogenesis, engineering-geological features, Podolian Upland.

The Fore-Carpathians part of Svicha River valley partially covers Morshyn and Zalissia Uplands and Stryi-Zhydachiv depression. Within the Svicha and Sukil' river valleys, there are well-developed different-age terraces with thick stratified loess covers. The investigation of the last ones can help to define nomenclature and age of the terraces. The loess covers of the third (Kolodiiv) and the fourth (Mariampil) terraces, which are represented by Pidberezhzhia and Mizhrichchia sections accordingly, are characterised in detail in the article. Pidberezhzhia section represents a sequence of alluvial and covering deposits of the third (Kolodiiv) over-floodplain terrace of Svicha River, which is developed on its right bank. The terrace is stretched out in the form of a narrow (about 2 km) strip from the village Zarichchia to the village Novoselytsia. It is separated from the Svicha riverbed by the system of different-altitude floodplain levels and the first and second over-floodplain terraces. The boundaries between them are morphologically distinct, the exceeding of the surface of the Kolodiiv terrace above the water level in the riverbed of Svicha reaches 10 m or even more. Covering loess-soil series on the terrace has a capacity of more than 6 m and begins with the Horokhiv fossil soil complex. Mizhrichchia section represents the fourth (Mariampil) over-floodplain terrace, which to the north of Mizhrichchia village forms a scarp to the riverbed of the Svicha River, about 20 m in height. The terrace on this part of the valley of the river covers small areas and it is developed between the villages of Zarichchia and Mali Didushychi. Almost along its length, the terrace directly scarps to the riverbed. On the opposite side, where the rear seam is, it borders on the fifth (Galician) over-floodplain terrace, which forms a scarp about 10 m in height. Loess cover on the fourth terrace is up to 14 m thick. There are welldeveloped Dubno fossil soil (MIS 3) and Horokhiv fossil soil complex (MIS 5) and a thick sequence of hydromorphic deposits, which obviously correspond to the Korshiv fossil soil complex (MIS 7) in loesspaleosol series. The studied Pleistocene covers allow us to reliably identify Mariampil and Kolodiiv terraces of the Svicha River, as well as outline the nomenclature of the remaining terraces of the adjacent sections of the Zalissia and Morshyn Uplands and Stryi-Zhydachiv depression. Key words: river terrace, loess-soil covers, Dubno fossil soil, Horokhiv and Korshiv fossil soil complexes, Fore-Carpathians, Zalissia and Morshyn Uplands.

Different Parts

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.

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. Key words: loess, loess-soil series, key section, fossil soil, engineering-geological features.

Detailed description of the loess-soil series from the key section at Zbarazh, situated on Chmelnytsky Upland, close to the Tovtry ridge, is given. The engineering-geological features of all the distinguished horizons and sub-horizons of the rocks were characterized, particularly subsidence of the rocks. It was proved that the formation of these features was influenced by palaeogeographic conditions of the deposition. In the Zbarazh key section traces of plastic (solifluction) and structural (pseudomorphs after polygonal-vein ice) paleocryogenic deformations were recognized. The section is a stratotype of the Zbarazh paleocryogenic event, which took place during the final stage of the Middle Pleistocene. Paleocryogenic deformations seriously influenced the features of the rocks of the loess-soil series. Key words: loess-soil series, palaeocryogenic deformation, engineering-geological features, key section.
