The morphosedimentary record of glacial to postglacial environmental changes in West Wiyâshâkimî impact crater lake and adjacent areas, northern Québec, Canada

Boreas, EarlyView.
Crater lakes in core regions of former ice sheets have the potential to preserve long‐term sedimentary archives that are otherwise rare in glaciated landscapes due to pervasive glacial erosion. Lake Wiyâshâkimî, an impact crater lake located in the inner core of the Québec‐Labrador Dome of the Laurentide Ice Sheet, provides a rare example of such a ...

Palaeoenvironmental changes recorded at the Velika Vrbica loess‐palaeosol sequence, Wallachian Basin, during MIS 3–MIS 1

Boreas, EarlyView.
This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χlf), and mass ...

Multiple indicators record human adaptations to climatic change during the Middle Holocene at the Wanbei site in the middle and lower Huai River valley, China

Boreas, EarlyView.
The archaeological sediment sequences analysis from the Wanbei site reveals a predominantly warm and humid climate with a brief cooling phase between 5600 and 5400 a BP, during the Middle Holocene in the middle and lower Huai River valley. Despite the cooling trend, rice remained the dominant crop in mixed farming, while the proportion of millet ...

Comments on ‘Late Middle Pleistocene Wolstonian Stage (MIS 6) glaciation in lowland Britain and its North Sea regional equivalents – a review’

Boreas, EarlyView.
Divergent views debated over the past 20 years on the Wolstonian depositional record of Fenland and the Peterborough area have centred on whether there is evidence of a single (middle or late) glaciation or of both a middle and a late glaciation. A recent review promoted a single late Wolstonian glaciation, despite there being incontrovertible evidence

A 3200‐year weathering record of the Mekong River basin by sediments from the South China Sea

Boreas, EarlyView.
The Mekong River is a mega‐river in East and Southeast Asia, and precipitation in its watershed influences more than 300 million people. However, the controlling factor in precipitation and weathering in the basin remains controversial. Here we present a high‐resolution record of weathering of the Mekong River basin over the past 3200 years by ...

Cave Palaeolithic of the Ural Mountains – a review

Boreas, EarlyView.
The Ural Mountains are of fundamental importance for studying early human migrations along the geographical limits between Europe and Asia. Geological processes and past climates gave rise to numerous caves, mostly in Palaeozoic carbonate formations.

Luminescence analysis of a postglacial landscape in northeastern Norway and northern Finland

Boreas, EarlyView.
Portable optically stimulated luminescence (pOSL) analysis allows rapid relative dating of sediments that potentially can be calibrated against known OSL ages to provide an age estimate for landforms across a large area. This study uses 186 pOSL measurements and 20 OSL ages to investigate the postglacial landscape evolution inside the Younger Dryas ...
