Check out this amazing discovery: Geologists have located a gigantic geode cave in an abandoned Spanish mine. How cool is that? Geode’s rarely get as large as a softball, and this one is a cave big enough to hold 10 people. Amazing.
Javier Garcia-Guinea, the geologist from the Spanish Council for Scientific Research in Madrid who found the cave, can find no other reference anywhere in the world to a geode of such enormous size. The cave measures 1.8 metres wide, 1.7 metres high and spreads 8 metres long. The abundant hydrous calcium sulphate deposits, better-known as gypsum crystals, are about a half-metre in length.
