Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

Boreas, EarlyView.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Single‐grain K‐feldspar luminescence dating on primary and re‐deposited aeolian sediments in Mongolia

Boreas, EarlyView.
Owing to its location in the semi‐arid region of northern Central Asia, Mongolia is highly sensitive to climate change and therefore provides an excellent setting for palaeoenvironmental research. Proxy data from different sediment types are crucial for interpreting past climate changes and landscape evolution, while burial ages provide chronological ...

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Morphometric analysis of cirques in central Siberia's western Putorana Plateau: a proxy for palaeoclimate

Boreas, EarlyView.
A detailed morphometric analysis of 200 cirques across the western Putorana Plateau, central Siberia, was undertaken to investigate cirque development, reconstruct glaciers and infer palaeoclimatic conditions. Cirques are amphitheatre‐shaped landforms with mean length and widths of 936 and 1000 m, respectively, indicating a mature glacial landscape ...
