Significance of the correlation between the electrical conductivity dataset and lithology in Pleni-Lateglacial and Holocene alluvial archives.A case study: the Choisille catchment (SW Paris Basin, France)

Introduction Alluvial floodplains constitute rapidly evolving sedimentary environments, registering both climate changes and human impact. In the Paris Basin, the floodplain filling is generally composed of two major units (Pastre et al., 2003; Macaire et al., 2006): coarse deposits (sands and gravels) from the Pleniglacial or Late Glacial in the lower part and fine deposits (clayey-silty to carbonated or peaty sediments) from the Late Glacial and Holocene in the upper part. Because of its hi..
