Abstract
Volcanoes of the Eifel district have sampled the total crust. From 1000 Xenoliths the following profile is deduced (downwards): 5 km devonian; 10 km greenschist facies phyllites; 5 km low amphibolite facies micaschists; 5–10 km medium to high grade amphibolite facies gneisses. A thin layer of granulite facies metabasites between these and the Moho are regarded as remainder of an older series, the other rocks have suffered Variscan Barrow-regional metamorphism. Many xenoliths display young contact metamorphism at deep chambers and short pyrometamorphism superimposed. The crust has suffered rotational deformation increasing downwards in amount and complication. Heating has not surpassed 300°C 15 km below the recent surface since Variscan times.
