nodule - (mineralogy) a small rounded lump of mineral substance (usually harder than the surrounding rock or sediment) mineralogy - the branch of geology that studies minerals: their structure and properties and the ways of distinguishing them.
Geodes (Greek Î³ÎµÏÎ´Î·Ï - ge-ÅdÄs, earthlike) are commonly independent spherical masses of resistant mineral matter that are usually hollow. The extreme filling of a geode so that it is solid is also common.Some people refer to completely in-filled geodes as nodules, but the two names are not always consistently used.eodes differ from nodules in that a nodule is a solid mass of mineral matter, but some nodules may have a tiny void space in their interiors and the distinction between a geode and a nodule may be barely discernible if the cavity is miniscule.
