Geochemistry of Lower Devonian terrigenous sedimentary rocks from the Belgian Ardenne: Source proxy and paleogeographic reconstruction
Major and trace element (Rb, Sr, Ba, Zr, Ni, V, Zn, Cr, Y, Ce) compositions are studied in Lower Devonian terrigenous sediments from the Dinant Synclinorium and Ardenne Anticline (Belgian Ardenne). Five cross sections encompassing 148 samples in19 formations have been studied. In the conventional [Al2O3+Fe2O3-K2O-Na2O]–[K2O]–[FeO+MgO] triangle, the rock compositions plot on the illite – chlorite tie line. This suggests that (1) the mineral association has reached equilibrium in the pressure and temperature range of the postdepositional evolution of the sediments; (2) the chemical system was op...
