Additional information | First formal description of the Röt Formation in Belgium. The stratigraphy of the red sandstones in the Belgian part of the Roer Valley Graben is hardly known , though it is probable that the gypsum-bearing red sand stones and shales belong to the Solling and Röt Formations of the Upper Germanic Trias Group, according to the Dutch Stratigraphic Nomenclature. However, the contact with the underlying Buntsandstein Formation , supposedly along Hardegsen Unconformity which marks the boundary between the Upper and Lower Germanic Trias Groups, has not been recognised and total thickness of the Triassic sandstones thus is not known with certainty. |
