Bonchkovsyj O. The sequence of the formation of the loess-palaeosol sections of the Volyn’ Upland.

The thesis deals with reconstructions of short-term Pleistocene environmental changes (in soils, sediments, cryogenesis, vegetation, climate) in the Volyn’ Upland which are based on a complex study of loess-palaeosol sections: sixteen of them are first discovered and two sections were previously known but undergone the new study. In the thesis a methodological approach is developed for the reconstruction of short-term palaeoenvironmental changes during the Pleistocene in the Volyn’ Upland by the synthesis of grain-size, geochemical, palaeopedological (especially micromorphological), palaeocryological, paleopalynological, palaeobiomic and palaeoclimatic methodologies. The block model of the step-by-step use of this approach is elaborated.
