Dendrochronologie : potentialités et nouveaux enjeux pour l’archéologie préventive

2019

International audience; La dendrochronologie, méthode de datation qui étudie la variation des largeurs des cernes de croissance des arbres, est sollicitée, en archéologie, pour l’obtention d’une date absolue. Elle nécessite un dialogue incontournable entre les différents acteurs de la discipline pour fiabiliser les acquisitions, voire tout simplement obtenir une date. L’analyse des bois archéologiques ne se limite toutefois pas à la seule datation et constitue le point de départ de nouvelles approches qui permettent de combler des espaces et des champs de recherche encore lacunaire, pour le sud de la France notamment. Dans le contexte des changements climatiques actuels, la dendrochronologi…

IDENTIFICATION OF BACTERIAL TAXA IN ARCHAEOLOGICAL WATERLOGGED WOOD

2014

Summary The microscopic and molecular techniques described in this study are aimed at understanding the degradation processes of the anatomical structure of submerged archaeological wood, correlating it to the degradation induced by bacteria. The SEM micrographs showed alterations of the wooden structure due to bacterial colonization, as well as the presence of pyrite framboids. The difficulty of extracting bacterial DNA from wooden fragments belonging to submerged finds is well-known, due to the presence of many inhibitors; this study describes some extraction and in vitro amplification protocols for wooden submerged finds. The results of the molecular investigations, based on the analysis…
