Middle Pleistocene seismically induced clay diapirism in an intraplate zone, western Brittany, France
The Brittany region of France is located in a low seismicity intraplate zone. Most of the instrumented earthquakes are limited to a shallow crustal depth without surface rupture. A paleoseismological analysis was performed on deposits on the Crozon Peninsula and in the Elorn estuary. We highlight hydroplastic deformations induced by liquefaction leading to clay diapirism, which were likely triggered by past earthquakes. This diapirism seems to be…
Coastal palaeoenvironmental record of the last 7 kyr BP in NW France
To date, Holocene palaeoecological signatures on the Northwestern coast of France have not been thoroughly investigated. In this study, environmental changes related to both climate processes and human disturbances were reconstructed over the last 7000 cal. yr BP, based on pollen and chironomid assemblages from four coastal cores retrieved in Western Brittany (Porsmilin beach, NW France). Pollen and chironomid records show an environmental respon…
Middle- to late-Holocene storminess in Brittany (NW France)
This study focuses on the recurring climate conditions required for the largest storms occurring in NW France (Brittany). It is based on the analysed records of storm events along Western Brittany coast (see Part I). In this manuscript (Part II), storm recurrence is explored along with forcing mechanisms. Periods of more frequent storm events over the two last centuries are analysed first in order to link these events with possible forcing mechan…
Middle- to late-Holocene storminess in Brittany (NW France)
Our study aims to understand the recurring climatic conditions prevailing during the largest storms reaching NW France (Brittany). These storms are responsible for the breaching of coastal barriers and major flooding of lowlands. In a first part of our work, we examine the morphological impact and stratigraphic record of storm events along Western Brittany rocky coasts, with a special focus on the southern coast of the Bay of Audierne, the most e…
Development and application of high-resolution petrography on resin-impregnated Holocene peat columns to detect and analyse tephras, cryptotephras, and other materials
Chironomid responses (Insect
Lateglacial to Holocene subfossil chironomids from the St-Omer basin at St-Momelin (northern France) were analysed. At the end of the Lateglacial, stratigraphic and chironomid sequences indicate a shallow, oligotrophic and slow-flowing freshwater stream, with abundant aquatic macrophytic vegetation. Cold-water adapted taxa indicate a cold climate. During the early Holocene, from about 9500 to 7700 conventional radiocarbon yr BP, climate improveme…
Apport de la thermoluminescence sur silex chauffes à la chronologie de site paléolithiques de Normandie
Since twenty years there was an important advance concerning the norman Palaeolithic essentially along the cliffs of the Cotentin peninsula and on the " plateaux " of Upper-Normandy (Saint- André " plateau ", Pays de Caux ..). The chronostratigraphy has been precised and also the technology of the lithic material The human structured space (hearth, accumulation of lithic material, lines of blocks, ditches) is now well known. But it was necessary …
Stratigraphy, age and formation of peaty earth hummocks (pounus), Finnish Lapland
Detailed investigations of peaty earth hummocks called pounus were carried out in northemmost Finnish Lapland in the vicinity of the Kevo Subarctic Research Station. Pounus are complex, often vegetated, cryogenic mounds formed partly of peat. Some have a core of mineral soil or several large stones, or just one frost-heaved boulder covered by peat. They belong to the same group of earth hummocks as thufur and non-sorted circles. The typology of p…
La coupe de Nantois (Baie de Saint-Brieuc, France)
Les loess déposés en période glaciaire au cours du Pléistocène peuvent être datés par la méthode de la thermoluminescence (TL). L'âge de tels dépôts coïncide alors avec la remise à zéro du signal de TL due à l'exposition des minéraux au rayonnement solaire lors de leur transport éolien. Les premiers résultats obtenus par cette méthode, sur la fraction éolienne du quartz, ont permis de dater des sédiments d'âge allant jusqu'à 100 ka (100000 ans) e…
Le gisement paléolithique moyen de Seclin (Nord)
La séquence observable à Seclin comporte les unités lithostratigraphiques caractéristiques des formations weichseliennes de versant dans la zone limoneuse occidentale du Nord de la France. L'ensemble inférieur (unités 6 à 9) présente des caractères sédimento- logiques et stratigraphiques qui le rattachent à l'unité lithostratigraphique des "Sables et limons". Cette unité est interprétée comme étant le bilan pédo-sédimentaire du Début Glaciaire we…
Le gisement moustérien d Hénin-sur-Cojeul (Pas-de-Calais)
The site of Hénin-sur-Cojeul (Pas- de-Calais) includes loessic deposits corresponding to the Middle Pleni- glacial (Weichselian) (isotopic stage 3). Occupation levels are preserved in a fossil soil complex interpreted as Hengelo and Denekamp intersta- dials. Pollen analysis shows the development of Betula in a steppe-like vegetation. The oldest 14C date gives 37 900 ± 1 800 years BP. The faunal remains are dominated by Bison. The lithics series a…
