How geochemistry tells about climate and environments

When I was a child my parents told me about the dormant volcanos in the Eifel, but I never had the opportunity to see them. So of course I could not resist joining the Eifel field trip after last week’s conference in Frankfurt. Although it’s not really the general subject of this blog I like to share some pictures, because it’s so much fun to learn something new.
