Diabas Volcanism in the Rhenish Slate Mountains: Foundation and Destroyer of Devonian Reefs

Lecturer: Prof. Wolfgang Bach

The rocks of the Rhenish Slate Mountains represent sedimentary and volcanic deposits from a peripheral sea south of the equator. During a very lively volcanic phase in the middle devon, sea mountains formed in this Rhenoherzyn Sea, on which riffatolle formed out of stromatopores and corals. The explosive nature of these volcanoes, however, also leads to the local destruction of the reefs. In the lecture, examples of the interactions between volcanism and reef development will be presented.
