“…The SiO 2 /TiO 2 ratio also shows a good agreement between BAK and SAG and the reference section of Kurortne (Black Sea Shore) in southwest Ukraine (Tecsa et al, 2020), which is visible in the K 2 O/Al 2 O 3 vs. SiO 2 /TiO 2 diagram as well (Figures 4,8). In general, two sediment pathways were reconstructed for Ukrainian loess covers.…”

The source of aeolian sediments such as loess has been investigated since decades. Reliable knowledge on potential dust sources is crucial to understand past climatic and environmental conditions accompanying the dispersal of early modern humans (EMH) into Europe. Provenance studies are usually performed on small sample sets and most established methods are expensive and time-consuming. Here, we present the results of high-resolution geochemical analyses performed on five loess-palaeosol sequences from the Lower Danube Basin (LDB), a region, despite its importance as a trajectory for EMH, largely underrepresented in loess provenance studies. We compare our results with geochemical data of loess-palaeosol sequences from Austria, Hungary, Serbia, and Ukraine. Based on published literature, we thus evaluate five plausible sedimentary pathways for the LDB loess: 1) the Danube alluvium (DA) pathway, which constrains the transport and re-deposition of detrital material by the Danube and its tributaries; 2) the Carpathian Bending (CB) pathway, where sediment is mainly transported from the Cretaceous to Neogene flysch of the Eastern Carpathian Bending; 3) the Eastern Carpathian (EC) pathway, in which sediment is eroded from the flysch of the Outer Eastern Carpathians, transported by rivers, and deflated by northwesterly to westerly winds; 4) the glaciofluvial (GF) pathway, where dust is deflated from glacial outwash plains in nowadays Ukraine, and 5) the Black Sea (BS) pathway, where dust originates from the exposed shelf of the Black Sea. Based on geochemical data, we consider the DA pathway to be the major sediment trajectory for loess in the LDB. Especially the sequences located close to the Danube and the Dobrogea show similarities to sites in Central and Northeast Hungary as well as Northern Serbia. For the northeastern part of the LDB, we demonstrate that dust input is mainly sourced from primary material from the Eastern Carpathians. Mineralogical estimations and geochemical data render the CB pathway as an additional substantial source of detrital material for the loess of this area. We consider the influence of the GF pathway in the LDB as negligible, whereas some minor influences of the BS pathway cannot be ruled out based on geochemical data.

Several new vertebrate and plant taphocoenoses of fluvial origin have been found in central Ukraine, within the area previously covered with till of the late Chibanian Dnipro glacier. These finds represent a timespan from the late Dnipro glacial to the Pryluky interglacial of the regional stratigraphic scheme of Ukraine and fill an important palaeofaunistic gap: arcto‐boreal species have been revealed for the first time in deposits of the Dnipro/Kaidaky, Tiasmyn and an intra‐Pryluky cold interval. Their appearance in the fossil record marks the most extreme periods of cooling, but even during these extremes arcto‐boreal forms did not dominate. Similarly, a few warm‐loving species appear only during interglacials. The tundra–steppe semblance of vertebrate fauna remains generally stable during this time. The new findings were also used to test existing correlation models between the stratigraphic scheme of Ukraine and Marine Isotope Stages (MIS). For this, we used the Arvicola interval‐zones: the zone of the extinct water vole Arvicola chosaricus, which, in the studied area, covers the Dnipro, Kaidaky and Tiasmyn stages, and of the extant A. amphibius of the Pryluky interglacial and subsequent time periods. In different parts of Europe, replacement between these two species took place from MIS 6–MIS 5 to MIS 5. This indicates that the Tiasmyn with the latest A. chosaricus might represent both MIS 6 and a cold interval within MIS 5. For further refinement of the correlation, we use the newly discovered taphocoenoses with a clear stratigraphic sequence, together with the previously studied Maksymivka locality. They have a clear stratigraphic relation to the Dnipro till, and together with the above‐mentioned climatic signal, these proxies support the correlation of the Dnipro glacial with MIS 6, the Kaidaky interglacial with MIS 5e, the Tiasmyn cold interval with MIS 5d, and the Pryluky interglacial with MIS 5c and younger.
