What is Metavivianite?

Metavivianite (Fe2(PO4)2(OH)2·6H2O) is a hydrated iron phosphate mineral found in a number of geological environments. As a secondary mineral it is typically formed from oxidizing and dehydrated vivianite. Metavivianite is typically found as dark blue or dark green prismatic to flattened crystals. It was named by C. Ritz, Eric J. Essene, and Donald R. Peacor in 1974 for its structural relationship to vivianite.
