Several sites in the South-west of France have delivered lithic remains belonging to the Middle Pleistocene. Even though this documentation is of great importance to the understanding of the lithic assemblage of the Lower and Middle Paleolithic, its study has until now been limited by the lack of precise chronological data. This work aims to bring forth precision to the chronological context of this region by applying optical stimulated dating in order to date sedimentary quartz from the sites of Vaufrey, Coudoulous I, Duclos and Romentères. Therefore, a methodological work was undertaken to expand the chronological limits of OSL dating on sedimentary quartz. It consisted on developing an approach based on the use of the TT-OSL signal. Furthermore an inter-comparative study between ESR and TT-OSL was undertaken. In addition, TL dating was applied to directly date the lithic industry of the sites of Romentères and Duclos. The bulk of data obtained from this work allowed to demonstrate the potential of the TT-OSL method and shed a new light on the chronology of each of the studied sites, and then, on the evolution of the lithic industries during the Middle Pleistocene

Extent and chronology of the Pleistocene permafrost in France : database of periglacial structures and OSL dating of sand wedges. by Eric Andrieux( )

During the Mid to Late Pleistocene, the land area affected by periglacial conditions expanded and contracted repeatedly over large surfaces in mid-latitude Western Europe. In such environments, permafrost or deep seasonal freezing of the ground formed typical features, which have been the subject of abundant research by geomorphologists. In particular, researchers attempted to reconstruct the maximal extent of Pleistocene permafrost based on field evidence. Although most reconstructions suggest that permafrost spread over part of France during the coldest periods of the Pleistocene, there is no agreement regarding the land surface affected. This is mainly due to the scarcity of field data used for mapping and to the questionable palaeoclimatic significance of certain periglacial features. In addition, permafrost modelling during the Last Glacial Maximum using Global Climate Models does not seem consistent with field data. To solve these issues, a database of Pleistocene periglacial features has been compiled from a review of academic literature and unpublished reports, the analysis of aerial photographs and new field surveys. Polygons, soil stripes, ice-wedge pseudomorphs, sand wedges and composite wedge pseudomorphs were included in the database together with their geographic coordinates, geological context, description and references. The distribution of the identified features was analysed with a GIS software and clearly indicates that large areas in France were affected by periglaciation, apart from the southwesternmost part of France and the Languedoc. Ice-wedge pseudomorphs do not extend south of 47°N which indicates that widespread discontinuous permafrost did not affect the land south of the Paris basin. The exclusive presence of sand wedges with primary infill between 45 and 47°N, mainly in the periphery of coversands, suggests that thermal contraction cracking of the ground occurred together with sand drifting in a context of deep seasonal frost or sporadic discontinuous permafrost, unfavourable for the growth of significant ground-ice bodies. However, the description of composite-wedge pseudomorphs below 47°N indicates that at least locally ice veins formed probably during exceptionally cold winters. To provide a chronological framework for thermal contraction cracking single-grain OSL measurements were performed on 33 samples taken in the sandy infilling of sand-wedges and composite-wedge pseudomorphs. Results suggest that multiple events were recorded within wedges. The extraction of the datasets using the Finite Mixture Model, which was developed to analyse statistically data comprising multiple components, allowed calculating 86 ages. These age estimates show that wedge activity in France occurred at least 11 times over the last 100 ka. The most widespread events of thermal contraction cracking occurred between ca. 30 and 24 ka (Last Permafrost Maximum) and are concomitant with periods of high sand availability (MIS 2). Although most phases of sand-wedge growth correlate well with known Pleistocene cold periods, the identification of wedge activity during late MIS 5 and the very beginning of the Holocene strongly suggests that sand-wedges do not only indicate permafrost but also deep seasonal ground freezing in the context of low winter insolation. The previously published young ages yielded by North-European sand-wedges likely result from poor record of periglacial periods concomitant with low sand availability and/or age averaging inherent to standard luminescence methods. This work allowed us to propose a map of the maximum extent of Late Pleistocene permafrost in France, which partially reconciles field data with palaeoclimatic simulations. The remaining discrepancies may be linked with a potential time lag between the Last Permafrost Maximum (c. 31-24 ka) and the Last Glacial Maximum (21 ka) and to the already identified warm winter bias of the models

Caractérisation et modélisation d'objets archéologiques en vue de leur datation par des méthodes paléo-dosimétriques : simulation des paramètres dosimétriques sous Geant4 by Loïc Martin( )

1 edition published in 2015 in French and held by 1 WorldCat member library worldwide

The paleodosimetric dating methods allow to obtain the age of some mineral materials which behave as natural dosimeters, the age being derived as the ratio of the dose accumulated from the dated event and the natural dose rate to which the sample was subjected.. The determination of the dose rate is usually based on simple models which only allow explicit calculations, but these models reproduce very imperfectly the diversity of situations encountered. Computer modeling allows to represent more complex and more realistic models, which lead to numerically simulate the dose rate. In this work, the toolbox Geant4, allowing to simulate particle-matter interactions by the Monte-Carlo method, was used to create complex models , as well as modeling tools accessible and adaptable to different types of samples and dosimetric situations. Simulations were first made with basic models in order to study the origin of dose rate variations in sediments, highlighting the limits of the simple models commonly used. This information was used to guide the development of modeling tools based on the Geant4 codes, and also to specify the protocols of samples analysis for gathering the data needed for numerical simulations. The DosiVox software allows to easily model a wide variety of samples through a voxelised representation of the object and its environment, and to simulate the radioactivity for calculating the spatial distribution of the dose rate. It was developed with a view of accessibility and current use. Comparisons with dosimetric situations previously studied or measured showed the relevance of the modelings, and the possibilities of this computer tool are exposed through a series of examples and applications. The characterization of the beta dose rate distribution in heterogeneous sediment is one of the most complex problems to be treated. In addition to a study aims at assessing the potential of DosiVox to consider these situations, the DosiSed software was developed specifically for modeling poly-mineral sets of grains. This tool was used to study the heterogeneity of the dose rate in real samples and allowed to include some of the results in a dating problematic

Les feldspaths comme support pour la datation par luminescence de gisements archéologiques et de séquences quaternaires d'Aquitaine by Marine Frouin( )

1 edition published in 2014 in French and held by 1 WorldCat member library worldwide

Les données chronologiques disponibles pour les gisements du Paléolithique moyen du Sud-Ouest de la France font état d'un manque de jalons chronologiques fiables. Pour ces périodes anciennes, l'établissement d'un cadre chronologique nécessite un investissement méthodologique important dans le domaine de la datation numérique. Les résultats obtenus dans cette étude reposent essentiellement sur la datation par luminescence optique de grains de feldspaths et de quartz contenus dans les sédiments. En particulier, l'étude des signaux de luminescence classiquement exploités (IRSL, pIR-IRSL), nous permet de mieux évaluer la fiabilité des datations à partir des feldspaths potassiques. Un protocole de datation fondé sur l'exploitation du signal de radioluminescence (IR-RF) de ces minéraux a aussi été développé. Ainsi, la luminescence optique a été appliquée à des échantillons provenant de six gisements de référence : Les Pradelles (Marillac, Charente), Combe Brune 2 (Creysse, Dordogne), Roc de Marsal (Campagne, Dordogne), Artenac (Saint-Mary, Charente), La Quina (Gardes-le-Pontaroux, Charente) et La Ferrassie (Savignac-de-Miremont, Dordogne). La combinaison des résultats obtenus nous a permis, au sein de chaque niveau archéologique, d'évaluer la pertinence des datations et de proposer pour chaque gisement un scénario chronologique qui nous semble fiable. À l'issue de cette étude, les occupations humaines, caractérisées selon leurs industries, ont pu être replacées sur une échelle des temps en regard des variations paléoclimatiques et paléoenvironnementales régionales. Plusieurs constats ont été dressés enrichissant le registre de nos connaissances sur les cultures néandertaliennes
