The Mesoproterozoic sub-Heddersvatnet unconformity, Telemark, South Norway [PDF]

Bulletin of the Geological Society of Finland, 2005
The 1.51 Ga Rjukan group,Telemark, S Norway, is divided into felsic volcanic rocks of the Tuddal formation and mafic rocks of the Vemork formation. It is overlain by the sedimentary rocks of the Vindeggen group (1.50-1.17 Ga), starting with the arkosic ...

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Stratigraphic Occurrences of Sub-Polar Planktic Foraminifera in Pleistocene Sediments on the Lomonosov Ridge, Arctic Ocean

Frontiers in Earth Science, 2019
Turborotalita quinqueloba is a species of planktic foraminifera commonly found in the sub-polar North Atlantic along the pathway of Atlantic waters in the Nordic seas and sometimes even in the Arctic Ocean, although its occurrence there remains poorly ...

Pre-late Weichselian podzol soil, permafrost features and lithostratigraphy at Penttilänkangas, western Finland [PDF]

Bulletin of the Geological Society of Finland, 2009
The ridge-shaped Penttilänkangas accumulation in western Finland is glaciofluvial in origin: probably an ice-marginal subaquatic fan, reworked and covered with younger deep water, littoral, eolian and glacial sediments.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Sedimentation and lithostratigraphy of the Vuosaari multiple till sequence in Helsinki, southern Finland [PDF]

Bulletin of the Geological Society of Finland, 1995
A multiple till sequence interbedded with sorted sediments has been investigated at Vuosaari, Helsinki, Finland. The investigation was carried out using standard sedimentological procedures combined with microfossil analysis in order to determine the ...

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Lithostratigraphy of the Red Sea Region [PDF]

GeoArabia, 2005
ABSTRACT The onshore and offshore Saudi Arabian Red Sea region contains a series of lithostratigraphic units that have not previously been formally defined and described. Based on an intensive study of the succession, a lithostratigraphic scheme is proposed in a lexicon format that integrates biostratigraphic, sedimentological, seismic ...

An updated correlation of the Silurian strata in Estonia [PDF]

Estonian Journal of Earth Sciences
The correlation of the Silurian succession of Estonia with the global standard has long been considered reliable. However, new information, particularly on the distribution of microfossils, has changed our understanding of the Silurian stratigraphy in ...
