This paper investigates the time‐transgressive evolution of the Fennoscandian Ice Sheet (FIS) during the Late Weichselian glaciation. Recent models of the Last Glacial Maximum (LGM) strongly challenge a synchronous development of the FIS in the SW Baltic Sea area. Especially in northern Germany, a time‐transgressive LGM is controversial. We present...

The bay barnacle Amphibalanus improvisus (Darwin, 1854) has been found in Northern Germany in brackish marine sediments of the Holsteinian interglacial. Whereas the cause of the contemporary distribution of this species is anthropogenic and there is evidence that it has resulted mainly from shipping, the fossil findings demonstrate that A. improvis...

Northern Central Europe is dominated by the Late Pleistocene glacial landscapes, drained in the west to the North Sea by the Elbe River, and in the centre and the east to the Baltic Sea by the Oder, Vistula, Neman and Daugava Rivers. There are abundant lakes in the region and the Baltic Sea coast is shaped by cliffs, lagoons, spits, bay bars and be...

Conference proceedings related to the 3rd Annual millPOLstone Workshop held in Golẞen (Brandenburg, Germany) on 6-7 September 2023. The meeting took place as part of the implementation of grant No. 2019/35/B/HS3/03933 funded by the National Science Centre (Poland).

During a detailed archival query carried out for the implementation of the Koszalin sheet of The Geological Map of Poland, scale 1 : 200 000, cartographers from the Polish Geological Institute found original materials from a research borehole made in 1938 in the Dar³owo (Rügenwalde) region. It was determined that in the drill core, in sediments dat...

New data about timing of late Weichselian Scandinavian Ice sheet (MIS-2) in northeastern Germany - lithostratigraphic investigations of tills and OSL-datings of a deglaciation sequence (MIS-2)

Late Pleistocene deglaciation and Scandinavian Ice Sheet dynamics in NE-Germany and NW-Poland: new results from 10Be surface exposure dating from giant erratic boulders

Periglacial features and permafrost disappearance during in northern Poland and northeastern Germany

After the Last Glacial Maximum, a general retreat of the European Ice Sheet Complex (EISC) was interrupted by several ice margin standstills and readvances. Three main ice-marginal standstills were distinguished, each preceded by the ice sheet advance, corresponding in turn to Chodzież (17.7 ka BP), Pomeranian (16.7–16.8 ka BP) and Gardno (15.5–16....

The Younger Dryas (YD) was a period of rapid cooling, connected with a large-scale reorganisation of atmospheric and oceanic circulation in the Northern Hemisphere. It was expressed by partial reaggradation of permafrost in northern Central Europe, resulting in a return of periglacial conditions in the deglaciated area and a delayed melting of buri...

Central Europe was a periglacial zone with a discontinuous permafrost at the termination of the Last Glacial Cycle after the Last Glacial Maximum. Meltwater discharge of low-energy braided rivers decreased and after 14,450 cal years BP incised channel systems predominated. Successive warmings of Meinendorf, Bølling and Allerød Interstadials resulte...

Oscillation of an ice sheet can be accompanied by earthquakes due to local reactivation of pre-existing faults related to the ice loading. A sufficiently large magnitude of an earthquake can trigger seismic waves that may strongly deform susceptible sediment layers and can cause the development of soft-sediment deformation structures (SSDS). Morpho...

Geomorphologic investigation and dating methods as Optically Stimulated Luminescence (OSL) or Surface Exposure Dating (SED) are the most applied methods in reconstruction and chronologically defining of ice marginal positions. Though there is an increase in the availability of geochronometrical data over the past decades, the progression, timing an...

The overall objectives of the GREBAL project were to investigate the sedimentological traces of earthquakes (seismites) within Pleistocene successions and to combine seismic activity with the particular stages of Fennoscandian Ice Sheet development. The studies performed consist of (1) field work conducted in river valleys, coastal bluffs and sand...

OSL dating of glaciofluvial deposits MIS-2

The Weichselian (Last Glacial Cycle) palaeoclimate in Central Europe was quite diverse, with several recurrent temperate-to-cold intervals. Despite glaciations occurring during the pre-Last Glacial Maximum (pre-LGM) part of the Weichselian in Northern Europe, ice-free conditions with extensive fluvial and more limited lacustrine deposits prevailed...

During the Last Glacial Maximum (LGM) the European Ice Sheet Complex (EISC) advanced across the Baltic basin and occupied the northern part of Central Europe where the overall glacial landscape clearly shows that the Baltic Sea depression played a decisive role in controlling ice-movement directions. The area occupied by the ice sheet during the LG...

The northern region of Central Europe was occupied by a sector of the European Ice Sheet Complex (EISC) during the Last Glacial Cycle (LGC, Weichselian). This region is a gently undulated part of the Central European lowlands. It is subdivided into large natural and geographic units with a maritime influence, but increasing continentality inland an...

For the palaeo-ecological development and interpretation of the macrofauna (Bivalvia and Gastropoda) of the Eemian Sea in the southwestern Baltic Sea region (NE Germany), up to date studies and summarising assessments are largely missing. With the main goal of revising the Eemian marine fauna, the authors have undertaken numerous new samplings in r...

Climate instability in the Eemian Interglacial is gaining more and more evidence. One of such oscillations in the Beckentin record is indicated by the disappearance of the Cladocera and changes in macroremains at the beginning of E4a (Corylus phase). They confirm the shallowing of the reservoir, probably caused by climate changes, but not reflected...

Knowledge of the distribution, types and properties of buried soils, i.e. palaeosols, is essential in understanding how lowlands in northern central Europe have changed over past millennia. This is an indispensable requirement for evaluating long-term human impact including soil erosion and land-cover dynamics. In the Serrahn area (62 km2), a young...

This paper aims to combine the knowledge of more than 100 years of Quaternary research in Mecklenburg-Western Pomerania (Geinitz, 1922; Deecke, 1907; Schulz, 1967, 1971; von Bülow, 2000; Rühberg et al., 1995; Müller et al., 1995; Katzung, 2004; Kenzler et al., 2015, 2018) including a summary of the areas of specific interest, a general overview of...

Isostatic response of the Earth's crust as a consequence of the fluctuating extent of ice-sheet masses was accompanied by earthquakes probably due to local reactivation of pre-existing faults. Our study of a glacilacustrine and glacifluvial succession exposed on Rügen Island (SW Baltic Sea) indicates that some of the soft-sediment deformation struc...

A Quaternary succession near Dwasieden (north-eastern Rügen Island) is exposed in a coastal cliff. The succession is intercalated between two tills and contains three distinct levels displaying numerous soft-sediment deformation structures (SSDS). Level SSDS-1 shows well-defined (sharp) lower and upper boundaries, but the SSDS are spatially (both l...

Over recent decades a growing number of well-documented records from terrestrial last interglacial sites across central Europe have substantially improved our understanding of Eemian climate and landscape dynamics. Despite this progress, there are also large areas from which little information is available, thus constituting significant paleo-geogr...

“SEEsand” aims at assessing the technical feasibility and viability of the extraction of rare-earth elements (REE) from zircon minerals actually being mined as a by-product from off-shore aggregates. The research challenge is to separate the REE bearing zircon-fraction and to extract REE by means of chemical and microbiological leaching processes.

The fluctuations in the extent of the Weichselian ice sheet induced - and still induce - earthquakes, and thus also represent potential natural hazards. Understanding the character of glacio-isostatic rebound during the Quaternary can deepen the insight into the behaviour of ice sheets, and help to mitigate potentially negative consequences of pres...

The rare-earth elements (REE) comprise a group of critical chemical elements with special electronic, magnetic, optical and catalytic properties that are crucial for a range of EU high-tech industries, including the automotive, wind-energy, electronics, and metallurgy sectors. Conventional REE mining from monazite and bastnaesite minerals in these...

“SEEsand” stands for REE production out of running off-shore aggregate extraction.

Periglacial areas are those which, although not actually glaciated, have been exposed to very cold conditions with intense frost action and the development of perennially frozen ground or permafrost. At the time of the maximum Late Weichselian glaciation, very harsh climatic conditions prevailed. it is possible to identify many landscape features o...

ICOP 2016 - LOCAL EXCURSION #4 - ICE AGE HISTORY OF NORTHERN GERMANY, MECKLENBURG From Eemian to Late Weichselian glaciation - ice age landscape of region Neubrandenburg/Feldberg

The marine sediments of the Eemian interglacial in the area of the Baltic Sea often contain a wealth of molluscs. In most publications about the Eemian fauna for more than one hundred years, Acanthocardia echinata has been listed almost exclusively. New sampling by the authors in Mecklenburg-Western Pomerania (NE Germany), especially in sediments o...

A novel occurrence of an Eemian interglacial peat was identified in 2011 in a short-lived outcrop of the NEL-pipeline trench, near the village of Banzin, Germany. The profiles are situated in a shallow kettle hole within the undulated landscape of the Saalian glaciation. The distribution of dominantly till lithofacies in the Banzin area confirms th...

Northeastern Germany was repeatedly covered by the Scandinavian Ice Sheet during the last glaciation and a succession of distinct ice marginal belts is present in Mecklenburg-Western Pomerania.

The maximum ice-sheet extent of a glaciation or glacial phase is in most cases indicated by the position of end moraines. In some cases, however, the maximum extent of the ice sheet is indicated by a fan which represents the transitional zone between the end moraine and the proximal outwash plain (sandur). Such a fan from the Pomeranian phase near...

description of Pomellen sand/gravel pit: subglacial glaciofluvial channel filling

Corresponding biostratigraphical and lithological evidences permit to conclude that the drilled Eemian sediment was formed predominantly in fluviolacustrine faciès in stagnant river lakes. The mollusc faunas investigated, therefore, is also of supra-regional significance and contains many mollusc species of the interglacial fluviolacustrine type. T...
