Geo Advent Calendar Day 7

Yet another purchase from the Festival of Geology features today. This rock was formed during a meteorite impact in Germany during the Miocene. Next summer I will be going to this impact crater during the final fieldtrip of my degree – since I have this impact breccia, I’ll know what to look out for when I’m in the field!07-suevite
