The inside of this geode is covered in xenosilicate.
Aside from its substantial material value, it is of great scientific interest, raising new questions on the genesis of xenosilicates as geodes were not thought to occur previously.
Why Blue Planet?
Honestly? Because we otherwise would have had no Blue Planet entry for Loot-a-Day. Our plan for today’s topic was simply to do a geode. And so it became a geode for Blue Planet.
Loot-a-Day is a month-long German blogging challenge by fellow German blogger Greifenklaue, who was inspired by ArtifactaDay which we ran last August as a counterpoint to RPGaDay in Germany. We followed up on this with two more marathons of daily content about artificial creatures and science-gone-too-far, respectively, and now Greifenklaue seeks to spread the format.
