IntroductionPetrologically the Kaiserstuhl is an alcali-carbonatite volcano that erupted about 16-19 million years ago in the Miocaene. There have been many pyroclastic flows and lava flows around the volcanic complexe. Some of the subvolcanic intrusions form the todays parts of the volcano. This stratovolcano originally had an altitude of 1000 - 2000 m. The Rhein river graben system was one of the causes why there was volcanic activitiy around the area of western "black forest" / Schwarzwald.
The volcano complex Kaiserstuhl is situated in the south west of Germany near the city of Freiburg. It is one of the most interesting volcanoes in Germany and for example...
