Tertiary and Quaternary Volcanism
Tertiary and Quaternary volcanic events occurred in several regions in Germany, some of them continuing into the Holocene and not completely extinct to this day. One of the most recent eruptions was that of the Laacher See volcano of the Eifel area occurring just ca. 13,000 years ago. In addition to the two active centers of Eifel volcanism, there existed a number of other Tertiary volcanic fields often related to tectonic structures. These include the volcanic rocks of the Kaiserstuhl, located in the Upper Rhine Graben, and the volcanics of the Eger Graben area.
