- Alvanite — A formal variant or structural feminine adaptation of the term 'alvanit', sometimes used in older technical literature or mineralogical translations; a rock or mineral aggregate composed predominantly of this hydrated vanadate. It represents a compound of purely scientific and collecting interest due to its extreme rarity in the Earth's crust.
