Late Famennian correlation by miospores between the Refrath 1 borehole (Bergisch Gladbach-Paffrath Syncline, Germany) and the reference section of Chanxhe (Dinant Syncline, Belgium)

Abstract

The Bergisch Gladbach-Paffrath Syncline and the Dinant Syncline are both part of the Ardennes-Rhenish Massif but are separated by some 100 km. In the Upper Devonian succession of the Bergisch Gladbach-Paffrath Syncline (The Bergisches Land), the Knoppenbissen Formation is assigned the "Dasbergian" (Hartkoph-Fröder et alii, 2004). In this syncline the thermal alteration index (TAI of 2 to 2+) is remarkably low compared to that of other Upper Devonian sediments in the Ardenne-Rhenisch area.
