Opis:
Tills in fluvioglacial cone of Sucha Woda Valley near Toporowa Cyrhla and Niżnia Palenica Pańszczykowa were recognized during mapping Tatra Mountains in scale 1 : 10 000. Tills with big boulders occur outside maximum range of Würm Glaciation end moraines and probably were accumulated by glacier of Riss Glaciation. Grain size composition, petrographical content (grains 5–10 mm) and compositions of heavy minerals (grains 0.1–0.25 mm) were investigated in tills. Dusty and clay fraction prevails (50–70%) above sandy and gravel fraction in these sediments. Gravel of granite without sandstone predominates in samples from Toporowa Cyrhla and gravels of sandstone with granite prevail in deposits of Niżnia Palenica Pańszczykowa. Granite in tills deposits occur in upper part of Sucha Woda Valley near Hala Gąsienicowa. Sandstone occur in middle and lower part of valley. Different petrographical content of samples from Toporowa Cyrhla and Niżnia Palenica Pańszczykowa could indicate various glaciers accumulated tills or various age of investigated sediments. Non-resistant minerals and magnetite prevail among heavy minerals. These investigations suggest glacial origin of these deposits and delimit bigger range of glacial tills by this day.

Opis:
A new borehole in Rożce (SW Mazovian Lowland) drilled in 2012, combined with a wide variety of research methods (palaeomagnetism, palynological analysis, studies of plant macroremains and textural features of deposits) shed new light on the age and stratigraphic position of the Early Pleistocene deposits, formerly assigned as the Lower Pleistocene. The study focuses on the deposits from 50.7-104.0 m depth, between glacial till of the Nidanian Glaciation (ca. 0.9 Ma) and the Poznań Clays (ca. 5.322 Ma). The deposits situated directly underneath the till (50.7-60.2 m) are related to the Nidanian Glaciation and show a reversed polarity and correlate with the end of the Matuyama Epoch. The deposits from 60.2-104.0 m depth were accumulated during the Early Pliocene, i.e. approximately 5.332-4.6 million years ago. They appear to correlate with the middle part of the Gilbert Palaeomagnetic Epoch and thus they are considerably older than previously thought. The cored section indicates a stratigraphic gap of about 3.5 Ma from the Lower Pliocene to the first advance of the Scandinavian ice sheets into Poland, which are thought to have occurred in the early Middle Pleistocene. The analysed deposits accumulated under variable climatic conditions showing two periods with significant aridity alternated with two periods of increased humidity. Deposits of the arid periods contain no pollen, butaeolian sand quartz grains are found. During periods of more humid climate the area was covered by various types of mixed forest.

Opis:
The Stajnia Cave is one of the most important archaeological sites due to the finds of the first remains of Neanderthals in Poland, and several tens of thousands of flint artefacts from the Middle Palaeolithic. Based on geological, geochemical, palaeobotanical, palaeozoological, archaeological and isotope analyses, coupled with absolute age determinations (OSL, U-Th and C14), 15 lithostratigraphic layers were distinguished and palaeoenvironmental conditions during the sedimentation of these beds were determined. The cave loams accumulated through weathering, aeolian and fluvial processes. Their age may be correlated with an interval from the Early Glacial to the Late Pleniglacial of the Visulian (Weichselian) Glaciation. Archaeological relics related to the Neanderthals have been discovered in layer D with an absolute age of about 52,000–45,000 years BP and correlated with MIS 3 – the Middle Plenivistulian (Interplenivistulian). Climate oscillations in the Vistulian are reflected by the type of the sediments and their physical-chemical features, allowing determining warmer interstadial and colder stadial periods. Generally, the climate was cold, characteristic of tundra areas with a typical vegetation and fauna, and with the mean temperature of the warmest month not exceeding 12°C. Based on multi-proxy studies it can be concluded that from layer E1 upwards, the climate conditions became progressively drier. At that time, the climate was cold with continental features enhancing tundra domination. This conclusion is confirmed by palaeontological investigations and the record of stable oxygen isotopes in the teeth of reindeer. The studies have also indicated seasonal migration of reindeer on the tundra that surrounded the cave. Probably, short-term slight climate warmings occurred during the Middle Plenivistulian (Interplenivistulian).
