In the section Vanzhuliv, the loess-soil series of the northern part of the Podillia Upland is exposed. In this section, the thickness of the Upper Pleistocene loess deposits is still relatively considerable, whereas the thickness of the Middle Pleistocene loess deposits increases. The detailed description of the section and of the engineering-geological properties of all the distinguished horizons and sub-horizons is given. Besides that, the influence of the large-scale fossil permafrost structure on the properties of loess is described, basing on the example of the pseudomorphic structure of the Lanivtsi paleocriogenic stage. Key words: loess, paleosoils, engineering-geological properties, subsidence, paleocriogenesis, Podillia.

The “Novovolyns’k” profile represents the NW part of the Volyn’ Upland with a typical loess relief and a thick Upper Pleistocene loess-soil series that has distinct stratification and wide development of palaeocryogenic deformations (structural as well as non-structural). The results of the engineering-geological study are discussed for each horizon of the soil-loess series/ Namely their individuality manifested in the high values of humidity and density, and in almost complete absence of subsidence. The properties of the rocks in the profile are correlated with the properties of the rocks from other profiles at the Volyn’ Upland. Key words: loess-soil series, engineering-geological properties, loess, palaeosoil, palaeocryogenic horisons.

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.

The article presents information about of the work of the International Scientific School on Paleopedology for Young Researchers. This school was conducted for ten years in Siberia in the Altai region, where unique Pleistocene loess-soil series are common and paleosoil horizons and modern soils are present simultaneously in one and the same soil profile. For ten years leading Russian and foreign scientists gave lectures both on fundamental theoretical and applied issues of paleopedology, as well as on a number of topical issues of related sciences, conducted master classes on the basic methods of field study of paleosols, and young researchers discussed their ideas and results. The article lists the main themes of the lectures/ naming Russian and foreign scientists who read them. It also informs about the monograph “Paleosols, the natural environment and methods for their diagnosis”, based on selected lectures at the School from its start until 2014 and published in Russian. Other selected lectures were published in two languages (Russian and English) in the series “Paleosols – a source of information about the Past environment”. The aricle draws attention to the key site "Volodarka" as being of great importance not only for conducting field master classes, but also as a convenient training ground for scientific research, since there occur various soil environment that can serve as models created by nature itself.

There is total thickness of loess-soil series approximately is 30 meters in this section. This key section is stratotype of Korshiv fossil soil complex and Lutsk fossil soil. Pseudomorphs after the structures of cellular ice of several stages of Middle Pleistocene palaeocryogenesis were allocated here for the first time for Volhyn-Podillia. Detailed description of the section and the results of engineering-geological studies of rocks of all selected loess and palaeosoil horizons were done. Individual properties of selected stratigraphic horizons and their dependence on the paleogeographic conditions of sedimentation were displayed. Key words: loesses, fossil soils, palaeogeographical conditions, engineering-geological features, subsidence, Volhynian 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.
