Greetings, I am selling some of my collection of mined Keokuk geodes. These geode were mined from the Jacobs geode mine in Hamilton, Illinois in early 2016. These geodes have beatuful shades of blue, gray, white, and clear.

These geodes were hand mined and placed in buckets then hand carried a short distance to my vehicle. I avoid bumping and jaring them. I hand clean them one at a time prior to bagging and storage in plastic bins.

DESCRIPTION:
Geodes (Greek γεώδης - ge-ōdēs, "earthlike") are geological secondary structures which occur in certain sedimentary and volcanic rocks. They are themselves of sedimentary origin formed by chemical precipitation. Geodes are essentially hollow, vaguely spheroid to oblate masses of mineral matter that form via either of two processes: By the filling of vesicles (gas bubbles) in volcanic to sub-volcanic rocks by minerals deposited from hydrothermal fluids orby the dissolution of sedimentary nodules or concretions (that were deposited syngenetically within the rock formations in which they are found) and partial filling by the same or other minerals precipitated fromdiagenetic water, groundwater or hydrothermal fluids.

Thank you for looking,
Myke
