Clay mineralogical and geochemical expressions of the "Late Campanian Event" in the Aquitaine and Paris basins (France): Palaeoenvironmental implications

Campanian sediments from two French sedimentary basins were studied, using clay mineralogy and stable isotope (δ13C and δ18O) geochemistry, in order to investigate the Late Campanian Event. The clay fraction of the Campanian sediments from the Tercis-les-Bains section (Aquitaine Basin) and from the ...
