The stratigraphy of the type locality of the ?Late Wenlock/Early Ludlow Mont Godart formation and the Early Ludlow Ronquières formation, Brabant Massif

The Silurian of the Brabant Massif crops out in the Sennette valley, near Ronquières. From these outcrops, the Mont Godart Formation is defined and the formerly poorly defined Ronquières Formation is redescribed in detail. Seven informal units, four of them divided into subunits, are distinguished in the Ronquières Formation. Based on Chitinozoa and graptolites, the age of the Mont Godart Formation is estimated possibly latest Homerian (Wenlock) or earliest Gorstian (Ludlow) and that of the Ronquières Formation as Gorstian (Ludlow). Four sedimentological facies occur: mud-grade turbidites pred... Mehr ...
