Abstract

The Proniatyn key section represents the loess-palaeosol sequence of the Upper and partially Middle Pleistocene of the Podolian Upland. A detailed description of the section is given, as well as the engineering-geological characteristics of the sediments of the loess-palaeosol sequence Proniatyn, which is quite well stratified. There are two horizons of the Upper Pleistocene loess and the upper horizon of the Middle Pleistocene loess have been clearly distinguished. The key section presents the Dubno (MIS 3) fossil soil, the Horokhiv fossil pedocomplex (MIS 5), as well as the well-developed deluvial-solifluction sediments over the Horokhiv pedocomplex, which contain a large number of redeposited Middle Palaeolithic artifacts. The engineering and geological features of sediments of the loess-palaeosol sequence Proniatyn have been studied in detail and compared with the characteristics of the corresponding horizons of the loess-palaeosol sequences of a number of sections of the Podolian and Volhynian Uplands. It is established, in particular, that in many aspects the loess-palaeosol sequence of Proniatyn key section is closer to the characteristics of sediments of the loess-palaeosol sequences of the Podolian Upland. The importance of studying the Proniatyn key section is enhanced by the fact that it is associated with the Middle Palaeolithic site, and in the structure of the Horokhiv fossil pedocomplex there are all sub-horizons of MIS 5. Furthermore, it contains a geophysical Blake event. Therefore, it is confirmed that the Proniatyn key section is an important stratigraphic benchmark of the Pleistocene of Podolian Upland. Key words: loess-palaeosol sequences, key section, Pleistocene, engineering-geological characteristics, solifluction, Palaeolithic.
