Are Geodes Metamorphic Rocks?

Geodes are technically sedimentary rocks, since they are the result of the action of water. Geodes are formed when cavities in a host rock (which may be sedimentary or igneous) become lined with a durable mineral, often a variety of quartz. The term geode usually refers to rounded nodules with hollow centers.

What type of rocks are geodes?

Geodes are more or less spherical or egg-shaped rocks containing a hollow cavity which is lined with crystals. They form in both igneous and sedimentary rocks. There are two major steps in their formation. A hollow cavity is formed in the rock.

Can geodes be metamorphic?

Regular geodes contain gems, and metamorphic geodes always contain rare prizes. Luck enhancers (ring of wealth, etc) now increase the chance for geodes to upgrade to metamorphic geodes.
