Abstract: Eifel Quaternary Volcanic Fields are an outstanding example of distributed, volcanic fields in an intracontinental setting. Highlights comprise ● Hundreds of cinder cones and maars distributed over two volcanic fields ● Episodic activity with cycles > 100 ka in both fields, last eruptions 12 ka ago ● 3 large, phonolitic centres in the East Eifel field, where the Laacher See eruption (LSV, 13 ka) had an explosivity index VEI=6 ● Shallow crustal reservoir of the LSV was active / hot during the last 30 ka ● Massive degassing of mantle CO2 (mineral water and production) ● Ongoing regional uplift today (GNSS and InSAR) driven by upper mantle ● A transcrustal magmatic system that covers large regions of > 100 km
