Geodes in sedimentary rocks are usually found in limestones dolomites and calcareous shale in these deposits a gas filled void can serve as the opening for geode formation. Crystals with small flat surfaces are said to have facets all crystals have a faceted surface but not all crystals have multiple facets. Igneous rock may form crystalline structures as it cools giving it a granular appearance.
