La formation du sol urbain : étude archéologique des terres noires à Tours (4e-12e siècle)

Abstract : This research is dealing with archaeological and geo-archaeological studies which, for thirty years in northern Europe, have partly renewed our understanding of medieval towns by analyzing dark earth layers. Not yet considered enough, this kind of deposit represents however an important historical record of ancient roman cities.
The study lay out both methodological and analytical interest. A method of creating and studying samples is explored, especially for archaeological stratifications in urban context. Experiences have been led on five excavations at Tours by analyzing fine and coarse composition of urban layers. The study is based on the principle that human activities are recorded in archaeological deposits. By applying site formation processes, developed for a long time in prehistoric and geoarchaeological researches, and by creating functional classification, the study allows characterization of human behavior which produced urban strata.
At the scale of archaeological sites, dark earth deposits attest specific activities: cultivated plots, domestic areas with ground refuse, open spaces and retrieval activities of construction elements have been identified. The study shows that dark earth deposits, which look like homogeneous soil layers, result in fact from diverse urban activities, which have been partly cancelled by post depositional processes.
At the scale of towns, dark earth produces evidence for cultural changes in urban lad-use. This study, integrated into urban archeological research developed since 1990's, contributes to a survey of new social practices of urban space from Late Antiquity, revealing new ways of constructing and living compared to classical towns.
