Comparison of high resolution XRF and downhole geophysical scanning of Nussloch loess records, Germany, with field observations
Nussloch (Germany) is a distinctive site of interest, particularly as a reference sequence for Late Pleistocene European loess, because it provides a comprehensive record of millennial climate variability. A notable feature of this site is its location within an active quarry. Consequently, the stratigraphic profiles documented constitute an ephemeral record, susceptible to rapid disappearance or brief accessibility, contingent on the operational…
Approaches and challenges to the study of loess—Introduction to the LoessFest Special Issue
In September 2016, the annual meeting of the International Union for Quaternary Research’s Loess and Pedostratigraphy Focus Group, traditionally referred to as a LoessFest, met in Eau Claire, Wisconsin, USA. The 2016 LoessFest focused on “thin” loess deposits and loess transportation surfaces. This LoessFest included 75 registered participants from 10 countries. Almost half of the participants were from outside the United States, and 18 of the pa…
Tsunami sedimentary deposits of Crete records climate during the ‘Minoan Warming Period’ (≈3350 yr BP)
Earthquakes or explosive eruptions generate tsunami, which are at the origin of thick and chaotic coastal sediments. These commonly fossiliferous deposits are formed instantaneously at the historical or geological timescale and therefore have the potential to provide snapshot records of past climates. In Crete, near the city of Palaikastro, crops out a 1- to 9-m-thick sedimentary layer deposited by a huge tsunami that has been previously estimate…
Rapid and cyclic aeolian deposition during the Last Glacial in European loess
The impact of Dansgaard–Oeschger cycles on the loessic environment and malacofauna of Nussloch (Germany) during the Upper Weichselian
A loess sequence has been sampled continuously at high resolution in Nussloch (Rhine Valley, Germany) for malacological and grain-size analyses between ca. 34 and 20 ka. Molluscan abundance and richness, percentage in hygrophilous species and grain-size index show cyclical variations related to the lithological loess–gley alternation. Major molluscan abundance maxima were triggered by temperature increases through an enhancement of the reproducti…
Paleoclimate Changes during the last 100,000 yr from a Record in the Brazilian Atlantic Rainforest region and Interhemispheric Comparison
A long terrestrial record, Colônia CO-3, from the Atlantic rainforest region in Brazil (23°52′S, 46°42′20 ʺW, 900 m a.s.l.) registrates variations in the forest expansion during the last 100,000 yr. The 780-cm depth core was analyzed at 2-cm intervals and arboreal pollen frequencies were compared to nearby speleothem stable isotope records and neighboring marine records from the tropical Atlantic. To evaluate regional versus global climate forcin…
Paléoenvironnements pléistocènes et peuplements paléolithiques dans le bassin de la Somme (nord de la France)
This paper represents a synthetic overview of the main results of the CNRS Programme " Palaeoenvironments and Hominids ". This project focused on the study of interactions between human occupation and environmental modification, between 500 and 10 kyrs BP, based on multidisciplinary and diachronic studies of key sites in the Somme Basin. The main analytic results concern ESR, TL-IRSL and 14C dates, which reinforce the chrono-stratigraphical inter…
Le gisement paléolithique moyen et les séquencess pléistocènes de Villiers-Adam (Val-d 'Oise)
Die 1996 beim Autobahnbau entdeckte mittelpaläolithische Fundstelle von Villiers-Adam mit ihrer pleistozänen Schichtenabfolge bot erstmals im Département Val-d'Oise die Gelegenheit fur eine multidisziplinäre Untersuchung. Der in die frühe Weichsel-Kaltzeit (105 000 BP cal.) datierte Hauptbelegungshorizont des Fundplatzes Petit Saule wurde auf einer Fläche von 3 866 m2 ausgegraben. Die Steingeräteindustrie des Platzes ist durch unterschiedliche Pr…
Paleoclimatic Reconstruction Using Mutual Climatic Range on Terrestrial Mollusks
Terrestrial mollusks, easily identified in Quaternary sediments, represent a reliable tool for quantitative estimates of environmental parameters. Our study, comparing the species distribution with meteorological parameters in Europe, shows that mean temperature of the coldest month and annual thermal magnitude are the most important forcing parameters. This survey allows us to adapt the mutual climatic range (MCR) method to terrestrial mollusk a…
Late Pleistocene Environments of the Central Ukraine
Late Pleistocene Environments of the Central Ukraine
The Vyazivok loess sequence from the Dnieper Plain, Ukraine, documents regional environmental changes during the late Pleistocene and Holocene. Pedological and palynological analyses and low-field magnetic susceptibility document changes from dense temperate forest during the last interglacial maximum to open, harsh, loess–steppe during the latest Pleistocene. The Vyazivok section overlies hillwash derived from a lower Pleistocene terrace and con…
Δ 13 C of Loess Organic Matter as a Potential Proxy for Paleoprecipitation
Paleoprecipitation reconstructions on the basis of pollen are well known, but they do not provide high temporal resolution for glacial periods. High-resolution paleoprecipitation reconstructions for the last glaciation based on the isotopic record organic matter in loess from Nussloch (Rhine Valley, Germany) are consistent with paleoprecipitation inferred from peat in the same area using an independant method. Thus, δ 13 C of loess organic matter…
Mollusk Record of Monsoon Variability during the L2–S2 Cycle in the Luochuan Loess Sequence, China
Molluscan changes that occurred in China over the S2–L2 upper middle Pleistocene series may be caused by monsoon variation. Study of terrestrial mollusks from the loess sequence in Luochuan, gathered in ecological groups according to the moisture and temperature requirements of the identified species, indicates alternating strengthened summer and winter paleomonsoons between 130,000 and 244,000 yr. The four occurrences of species, currently distr…
Late Pleistocene Climatic Variations at Achenheim, France, Based on a Magnetic Susceptibility and TL Chronology of Loess
New field investigations of the Achenheim sequence (Alsace, France) allow for the characterization of variations in the low-field magnetic susceptibility over most of the last climatic cycle, i.e., the past 130,000 yr. New stratigraphic data and thermoluminescence measurements permit reassessment of the previous chronological interpretation of the Upper Pleistocene at Achenheim. A high-resolution analysis of magnetic susceptibility discloses the …
Late Pleistocene Climate Record in the Eustis Loess Section, Nebraska, Based on Land Snail Assemblages and Magnetic Susceptibility
Based on multivariate analysis of mollusk assemblages and magnetic susceptibility of the Eustis section in western Nebraska, the climate of the Peoria loess steppe was relatively mild and, in terms of annual precipitation, relatively moist during the advance stages of Woodfordian ice. It was cold and dry during ice retreat. The diversity and composition of mollusk species indicates that the extreme cold and dry climate was reached during the late…
Holocene Environmental Signals from Mollusk Assemblages in Burgundy (France)
The malacofaunas of Burgundy, France, reflect changes in climate and the activities of man during the Holocene. Statistical analyses based on the Shannon diversity index and correspondence analysis are used to describe the mollusk assemblages in a composite sequence based on three well-dated sites. The variation demonstrated by the mollusks suggests that a two-step warming took place between 10,000 and 9000 and 8000 and 6000 yr B.P. in relative a…
Climatic transfer function from quaternary molluscs in European loess deposits
Correspondence and multiple regression analysis of terrestrial molluscs in the loess sections of Achenheim (Alsace, France) has permitted the reconstruction of climatic variations during the last three glacial-interglacial cycles back to 339,000 yr B.P. The sequence has been dated according to the SPECMAP chronology of Imbrie et al . (1984) and the fossil faunas have been calibrated in relation to recent assemblages sampled in defined ecological …
La retouche Quina
The Quina retouch does not seem to correspond with a clear definition. With what this really agree ? The experimentation joinded to a detailled statistical study of side-scrapers of La Quina (Charente, France) annihilates a restrictive typology. With this view the Quina retouch does not have to be individualized within the scaled retouch sensu lato. More detailled studies of the flaking and of the retouch have to be done together
