Abstract

Four distinct levels with oolithic ironstones represent useful marker beds which may be correlated with red/purple-stained shales and limestones of the Aachen area and of the southern borders of the Dinant Nappe. The ironstones (allochtonous ferruginized allochems) originated in a coastal area from which they have been removed by storm waves to the open shelf. A working model for their origin is proposed. Discussion of their paleogeographic value (indicators of geotectonic activities), the stratigraphic hiatus and the metalliferous deposits.-(LW).
