1. Geode

   A geode (; from Ancient Greek γεώδης (geṓdēs) 'earthlike') is a geological secondary formation within sedimentary and volcanic rocks. Geodes are hollow, vaguely spherical rocks, in which masses of mineral matter (which may include crystals) are secluded. The crystals are formed by the filling of vesicles in volcanic and subvolcanic rocks by minerals deposited from hydrothermal fluids; or by the dissolution of syn-genetic concretions and partial filling by the same or other minerals precipitated from water, groundwater, or hydrothermal fluids.

1. geode

   A geode is a rock formation that occurs in sedimentary and certain volcanic rocks. It features a hollow cavity lined with inward-growing crystals such as quartz, calcite, or even amethyst. The outer layer of a geode is typically unremarkable and ordinary-looking, while the inside can be filled with beautifully colored and structured crystals. They are often formed in volcanic rock or in layers of sediment where limestone or dolomite are present.

1. Geode

   Geodes are geological secondary structures which occur in certain sedimentary and volcanic rocks. Geodes are essentially hollow, spherical to oblate masses of mineral matter that may form from either the filling of vesicles in volcanic to sub-volcanic rocks by minerals deposited from hydrothermal fluids, or by the dissolution of sedimentary nodules or concretions and partial filling by the same or other minerals precipitated from diagenetic or hydrothermal fluids. Geodes differ from vugs in that the former were formed as early, rounded, structures within the surrounding rock, whereas vugs are irregular voids or cavities within a cross-cutting formation, usually a vein or breccia. Geodes also differ from "nodules" in that a nodule is a mass of mineral matter that has accreted around the nodule nucleus. Both structures had the minerals contained within, deposited from groundwater or hydrothermal processes. Geodes commonly have a chalcedony shell lined internally by various minerals, often as crystals, particularly calcite, pyrite, kaolinite, sphalerite, millerite, barite, dolomite, limonite, smithsonite and quartz, which is by far the most common and abundant mineral found in geodes. Geodes are found mostly in basaltic lavas and limestones. The Warsaw Formation in the Keokuk region near the area where Missouri, Iowa, and Illinois join contains abundant geodes.
