Geodes can occur in both sedimentary and volcanic rocks. Geodes are essentially hollow masses of mineral matter that may have formed from either of two different processes:
-By the filling gas bubbles in volcanic to sub-volcanic rocks by minerals deposited from hydrothermal fluids.
-By the dissolution of sedimentary concretions within the rock formations these can partial fill with the same or other minerals precipitated from chemical changes occurring during the conversion of sediment to sedimentary rock.
Geodes commonly have a chalcedony shell lined internally by various minerals, often as crystals, particularly Calcite, Pyrite, Kaolinite, Sphalerite, Millerite, Barite, Celestite, Dolomite, Limonite, Smithsonite, Opal, Chalcedony. Quartz and Amethyst are by far the most common and abundant minerals found in geodes.
