| Abstract [eng] |
The aim of the present research was to evaluate the influence of geological structure on the development of geomorphological complexes (regions) based on the case study of South Lithuania. The overview of investigations discusses the fields of investigations carried out by other authors: structural geomorphological, sub-Quaternary and Pleistocene palaeosurfaces, palaeogeographical post-glacial evolution, and geomorphological regionalisation. The sections “Methods” is devoted to regionalisation of sub-Quaternary surfaces, investigation of Pleistocene palaeosurfaces, reliability of distinguishing Pleistocene palaeosurfaces and evaluation of their comparability, and investigation of palaeogeographical evolution, and lithomorphogenetic structure of geomorphological regions. The dissertation introduces the general features of sub-Quaternary surfaces, distribution patterns of palaeoincisions, their genesis and filling material, palaeogeomorphological regionalisation of sub-Quaternary surface, thickness and specific distribution of Quaternary deposits and palaeosurfaces of the top of Dainava and Žeimena formations. The evaluating lithomorphogenetic structure of geomorphological regions allowed compiling map of lithomorphogenetic regions. The geological structure was correlated with the spatial distribution of geomorphological regions, the influence of sub-Quaternary surface and main Quaternary palaeosurfaces on the evolution of geomorphological regions was analysed. The obtained results are generalised in the section “Results”. The dissertation is comprised of 154 pages, 48 illustrations and 11 tables. |
