It was possible to define the turning point from extremely clayey and organic- rich sedimentation in the Early and Middle Holocene towards the deposition of coarser-grained and less organic overbank fines in the lower Pleiße valley near Leipzig, NW Saxony. This change occurred between 4000 and 3300 BCE more than 1000 years after the beginning of Early Neolithic settlement and was obviously linked with land clearance by the first farmers.
The landscape on the Black Sea coast of Georgia has changed significantly during the last few millennia. By using granulometric and geochemical analyses, we reconstructed significant sea level, coastline and palaeoenvironmental changes that have taken place in the surroundings of the Supsa fan since at least 4000 BCE.
This study presents ESR, OSL and C-14 data from Upper and Middle Pleistocene fluvial terraces (Übergangsterrassen, Hochterrassen) and its loess cover in the Bavarian Alpine Foreland. It will be illustrated that the ESR dating of embedded land-snail shells offers a new dating approach with an upper dating limit most probably much older than the penultimate interglacial (MIS 7). Furthermore, it shows that in some areas Hochterrassen gravels are underlain by older interglacial gravel deposits.
This paper is about deglaciation history in two areas of southern Norway. By dating rock surfaces we can estimate a minimum ice sheet thickness of 1476 m a.s.l. and a timing of deglaciation around 13 000 years ago in the western study area. In the eastern study area the deglaciation history is complex as the bedrock age most likely has inheritance from earlier ice-free periods. Comparing both study areas demonstrates the complex dynamics of the deglaciation in different areas in southern Norway.
The study evaluates the ability of stable isotopes (δ13C and δ15N) and sugar biomarkers to distinguish Erica from the dominant vegetation of the Bale Mountains in order to reconstruct the past extent of Erica on the Sanetti Plateau. No significant differences in stable isotopes are found between the dominant plant species. Although Erica is characterized by quite high (G+M)/(A+X) ratios, it cannot be unambiguously distinguished from other plants due to degradation and soil microbial effects.
Chemotaxonomic identification of keystone plant species in the Bale Mountains are possible using lignin phenols. However, Erica could not be differentiated chemotaxonomically from all other investigated plants using n-alkanes. Unambiguous characteristic patterns of lignin phenols reflected in the plant samples were not sustained in the organic layers and mineral topsoils. This is due to degradation and organic matter inputs by roots. Therefore, the past extent of Erica is still speculative.
This study combines geomorphological–hydrological analyses with the distribution of archaeological sites and obsidian raw material outcrops within the catchment of the Bisare River, Mt Damota, and Mt Sodicho (southwestern Ethiopian Highlands). The current highly dynamic hydrological system, strong recent sediment erosion, and increased human impact lead to land degradation, resulting in exposure of lithic raw material outcrops and destruction of archaeological material.
