Integrating age information from different localities for stratigraphic marker beds: application to the Eltville tephra (Western Europe)

Stratigraphic marker beds are often used in geosciences for regional and global correlation. For various reasons dating those layers directly proves to be difficult sometimes. In those cases ages from above and below such a horizon represent minimum- and maximum-ages. These are often determined from more than one location and this gives the possibility to combine these ages, test their consistency and finally derive an age in agreement with the findings from most localities. We present a novel approach to...

D1: Analysis of Migration Processes due to Environmental Conditions between 40,000 and 14,000 a BP in the Rhine-Meuse-Area, Sedimentology and Geochemistry ‒ Provenience analyses of loess-paleosol sequences

During the Aurignacian (35,000 – 30,000 BP) Homo sapiens arrived for the first time in the Rhineland and recolonized the region after the Last Glacial Maximum (LGM) in the Magdalenian (20,000 – 14,000 BP). The D1 Project is part of the "Collaborative Research Centre 806 (CRC 806) – Our Way To Europe – Culture-Environment Interaction and Human Mobility in the Late Quaternary“ (see Fig.1) and focuses on reconstructing environmental conditions during the last glacial cycle (40,000 -...

Evaluierung und Verbesserungspotentiale der Geochronologie basierend auf Löss-Paläobodenabfolgen des letzten Glazialzyklus im Rhein-Maas Gebiet

Im Fokus des Teilprojektes D1 des SFB 806 „Unser Weg nach Europa“ steht die Verbesserung des Verständnisses der Klima- und Umweltbedingungen während der ersten Ankunft des Modernen Menschen um 40.000 BP und seiner Rückkehr zwischen 18.000 und 12.000 BP im Westen Zentraleuropas. Zahlreiche Archive aus den Einzugsgebieten von Maas und Rhein ermöglichen anhand von komplexen Löss-Paläobodenabfolgen einen detaillierten Einblick in eine vielseitige Vergangenheit. Der zeitliche Fokus erstreckt sich von den...

A multi-proxy analysis of two loess-paleosol sequences in the Northern Harz Foreland

Within the second phase of the “Collaborative Research Centre 806 (CRC806) – Our Way to Europe – Culture-Environment Interaction and Human Mobility in the Late Quaternary” two loess-paleosol sections in the northern Harz foreland have been investigated. The region is part of the European loess belt, which closes up to the north with the northern loess boundary where Weichselian silt and sand sized aeolian sediments interlock. To the south the loess belt is limited by central German uplands. Here the...

Radiocarbon-dated megafauna from the Interpleniglacial in the western Lower Rhine Embayment, Germany – The finds from the loess deposits in the Coenen brick quarry (District of Düren) doi

Sites with informative megafaunal assemblages are rarely documented in the Lower Rhine Embayment. In the 1960’s many remains of large mammals were collected during sporadic salvage operations in the Coenen brick quarry in Körrenzig (District of Düren, Rhineland). AMS-14C dates place the find horizon into the Interpleniglacial (MIS 3). In the terrestrial records of the rhenish loess sections, deposits of this period are only preserved under very favourable conditions, particularly in the...

LUMINESCENCE DATING OF LOESS DEPOSITS FROM THE REMAGEN-SCHWALBENBERG SITE, WESTERN GERMANY doi

This study describes the luminescence characteristics of quartz of Upper Pleistocene loess of the Middle Rhine area. The loess/palaeosol sequence of the Schwalbenberg near Remagen comprises a multitude of interstadial soils and soil sediments that have been dedicated to the Marine Isotope Stage 3 (MIS 3). These weak calcaric cambisols and their derivates are underlain by loess and soil sediments of MIS 4 to MIS 5 and covered by loess sediments and intercalated gelic gleysols of MIS 2. We applied...

When the Desert Dried Up: Late Prehistoric Cultures and Contacts in Egypt and Northern Sudan

The western hinterland of Lower Nubia and Upper Egypt is desert, an area of extreme character, with little rainfall and sparse vegetation, nearly unpeopled and seemingly endless in its extension. Looking closer at that vast region, one recognizes that the desert is not that barren and simple but offers a diversified landscape and an enormous amount of archaeological traces of past human existence. Interest in prehistoric archaeology of the desert developed very slowly in Egypt and Sudan. Most of our...

The role of cryptotephra in refining the chronology of Late Pleistocene human evolution and cultural change in North Africa doi

Sites in North Africa hold key information for dating the presence ofHomo sapiens and the distribution of Middle Stone Age (MSA), Middle Palaeolithic (MP) and Later Stone Age (LSA) cultural activity in the Late Pleistocene. Here we present new and review recently published tephrochronological evidence for five cave sites in North Africa with long MSA/MP and LSA cultural sequences. Four tephra horizons have been identified at the Haua Fteah (Cyrenaica, Libya). They include cryptotephra evidence for the...

“Out of Africa” – Ausgrabungen in der ägyptischen Ostwüste (SFB 806: „Out of Africa“ – Excavations in the Egyptian Eastern Desert)

Die Ausbreitung des Menschen während der letzten 100.000 Jahre von Afrika nach Eurasien gilt heute als gesichert. Wissenschaftler diskutieren jedoch nach wie vor die verschiedenen möglichen Wege, die er dabei genommen haben könnte.
