A geode is basically a shape, not a specific mineral. Because quartz is very common in the Earth's crust, that is a common mineral they are made of, but calcite is also common. They were known in prehistory. Their primary use is by collectors. Keokuk Geodes (a specific variety found only in a small area of the Midwest USA) are mined by stripping away the Warsaw Shale that contains them and hand collecting the geodes. The mine is privately owned by the Shefflers, who formerly owned a rock & gem shop in the area. Much of the building material used for their shop was geodes. In some other areas, different mining techniques are used depending on the local geology. |

A geode is a formation, not necessarilly made of any given composition. It's like saying 'who makes red cars.' That being said, the majority of geodes are quartz and calcite. The vast majority of ones you see for sale have been dyed to look prettier. For uses: I've seen them used as lamps, bookends, and other semi-pointless display applications for pretty things. They've been around since long before human times, and finding out who 'discovered' them would be impossible. I know where some mines are - northern Mexico and the American southwest primarilly, although I have found some in the Black Hills of South Dakota as well. |
