Stratigraphy and dating of Middle Pleistocene sediments from Rodderberg, Germany

open access: yesJournal of Quaternary Science, Volume 39, Issue 7, Page 1011-1030, October 2024.
ABSTRACT The stratigraphy and dating of lacustrine sediments and loess derivatives from Rodderberg, a crater of the East Eifel Volcanic Field in Germany, is based on luminescence dating and incorporates radiocarbon ages, fingerprinting of key tephra layers of the East Eifel Volcanic Field (Rieden Tephra, Hüttenberg Tephra, Laacher See Tephra), pollen ...

Examination of Late Palaeolithic archaeological sites in northern Europe for the preservation of cryptotephra layers [PDF]

open access: yes, 2015
We report the first major study of cryptotephra (non-visible volcanic ash layers) on Late Palaeolithic archaeological sites in northern Europe. Examination of 34 sites dating from the Last Termination reveals seven with identifiable cryptotephra layers ...

Peat humification and climate change: a multi-site comparison from mires in south-east Alaska [PDF]

open access: yesMires and Peat, 2008
Peatland records of Holocene palaeoclimate have been widely used in Europe. Their potential in western North America remains largely unexploited despite an abundance of candidate sites.

The Distal and Local Volcanic Ash in the Late Pleistocene Sediments of the Termination I Interval at the Reykjanes Ridge, North Atlantic, Based on the Study of the Core AMK-340

open access: yesGeosciences, 2019
We made the geochemical analysis of the volcanic material from the sediment core AMK-340 (the Russian research vessel “Akademik Mstislav Keldysh” station 340), the central zone of the Reykjanes Ridge. Two ash-bearing sediment units within the

Estimating the frequency of volcanic ash clouds over northern Europe [PDF]

open access: yes, 2016
Fine ash produced during explosive volcanic eruptions can be dispersed over a vast area, where it poses a threat to aviation, human health and infrastructure. Here, we focus on northern Europe, which lies in the principal transport direction for volcanic

Some Basic Problems in Tephrochronology

open access: yesThe Quaternary Research (Daiyonki-Kenkyu), 1972
So much tephra deposits which are popularly called “Loam” or “Brown ash”, obscure discrimination of particular tephra layer from many others within the Quaternary section in Japan. Detailed description in petrography and in lithology is therefore needed for characterizing any particular tephra layers.

Historical and paleo-tsunami deposits on Kamchatka, Russia: long-term chronologies and long-distance correlations [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2001
Along the eastern coast of Kamchatka, at a number of localities, we have identified and attempted to assign ages to deposits of both historic and prehistoric (paleo-) tsunamis.
