Volcanic Styria

On October 17th, 5c visited Riegersburg for a combined biology and geology excursion on volcanic Styria. 

Dr. Ingomar Fritz, an expert on volcanism at the Universalmuseum Joanneum, led the excursion.

We had perfect, comfortable weather and a clear day that allowed us to see way into the distance. 

We learned about the two volcanic phases that occurred in the Styrian basin millions of years ago. We understood how the Riegersburg rock was formed and how a lake had once covered the ground we were standing upon. Dr. Fritz taught us about the type of volcano that formed the lake – the maar volcano.  We learned about igneous, sedimentary and metamorphic rock and about the volcanic tuff that is found in the region. 

Dr Fritz will receive a handmade thank you note from 5c.
