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 ...

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 ...

Reconstructing the complex history of a small-volume basaltic volcano (Ngatutura volcanic field, New Zealand) : The role of subsurface processes and implications for diatreme formation : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Earth Science at Massey University, Palmerston North, New Zealand [PDF]
, 2016 Monogenetic volcanism is very common on continents and often occur very close to civilisation. Limiting the ability of volcanologists to predict the location and extent of future eruptions at monogenetic volcanic fields is the lack of knowledge about ...

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

Depositional processes and stratigraphic evolution of the Campanian deltaic system of La Anita Formation, Austral-Magallanes Basin, Patagonia, Argentina [PDF]
, 2019 Coastal depositional systems are commonly classified in terms of the relative interaction of wave, tide and fluvial processes. The La Anita Formation represents the opportunity to study and better understand coastal sedimentary systems.

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 ...

Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

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.
