Une géode est une cavité rocheuse tapissée de cristaux (souvent automorphes) et d'autres matières minérales Ce n'est pas un minéral, mais une composition de formations magmatiques, cristallines et ou sédimentaires
- Geode (Geowissenschaften) – Wikipedia
Verbleibt bei einer Füllung durch Kristalle noch ein Resthohlraum, wird diese auch als Druse und bei vollständiger Füllung als Mandel bezeichnet In der Petrologie versteht man unter einer Geode eine meist konzentrisch aufgebaute Konkretion
- Geode - Academic Dictionaries and Encyclopedias
Geodes can form in any cavity, but the term is usually reserved for more or less rounded formations in igneous and sedimentary rocks, while the more general term "vug" is applied to cavities in fissures and veins
