摘要

In connection with the future Canal Seine-Nord Europe (Seine-Scheldt), a large-scale rescue archaeological survey was conducted between 2008 and 2011 in northern France. At Havrincourt (Pas-de-Calais), the discovery of several levels of Palaeolithic flint artefacts embedded in a relatively thick loess sequence (similar to 6-7m) preserved on a gentle slope facing north-east, has resulted in a rescue archaeological excavation on a total surface of 6 000 m(2). Four Palaeolithic levels were uncovered in primary position. This sequence has been the subject of a continuous stratigraphic survey over nine months and an interdisciplinary approach combining pedostratigraphy, sedimentology, micromorphology, palaeontology, malacology, environmental magnetism, OSL and C-14 dating. Based on this research, we propose: 1) a new pedostratigraphic reference sequence for Northern France, especially with regard to the Lower and Middle Pleniglacial periods (similar to 70-30 ka), 2) a new regional geochronological framework for the Last Glacial (luminescence and radiocarbon) as well as a revision of the regional pedostratigraphic and chrono-climatic systems, and 3) the description and dating of a unique succession of periglacial horizons including five ice-wedge cast networks associated with tundra gley horizons representing a first regional reference sequence. In addition, the good preservation of archaeological levels, associated with the multidisciplinary analysis and dating of the pedosedimentary sequences leads to the chronostratigraphic and chrono-climatic interpretation of the four Palaeolithic levels including a unique occupation related to the Early Upper Palaeolithic (Early Gravettian). These results and new discoveries allow us to propose Havrincourt as a new pedostratigraphic and archaeological reference sequence for the Late Pleistocene of northern France and more broadly for the west-European loess area.
