Volcanism of the Rhenish Massif and the Brabant Massif
The Hautes-Fagnes region is mostly build up out of slate, like the rest of the Rhenish Massif. The Hautes-Fagnes themselves are not remnants of old volcanoes. The Westernmost volcanic region of the Rhenish Massif is the Westeifel, where volcanism started to occur around 970.000 ± 100.000 years BP. This volcanic field contains about 240 monogenetic volcanoes. Around 500.000 years BP volcanism started to occur in the East Eifel region. This area has about 100 mostly monogenetic volcanoes. Between the East Eifel and West Eifel volcanism took place between 46 and 6 million years ago, in the region that we now call the 'Hocheifel' (High Eifel). This area has about 300 volcanoes. Other volcanism took place further to the East, in the Siebengebirge, Westerwald, Vogelsberg, Rhön, Heldburger Gangschar, and Niederhessische Senke. Of all the volcanic regions located in and around the Rhenish Massif, only the West Eifel and East Eifel are of Quarternary age.
Volcanism did occur in what is now Belgium, but the volcanic rocks that were erupted at that time are of Ordovician and Silurian age, and are located in the Brabant Massif, to the West of the Hautes-Fagnes.
