Meta-uranocircite is a hydrated barium uranyl phosphate mineral, transitioning from uranocircite through dehydration. Its chemical formula is Ba(UO₂)₂(PO₄)₂·6H₂O, compared to uranocircite’s more hydrated form with eight water molecules. This transition occurs naturally when uranocircite loses water, often in the oxidation zones of uranium deposits. Meta-uranocircite typically forms greenish-yellow tabular crystals or crusts and is associated with other uranium minerals. Radioactive and fluorescent under UV light, it is found in regions with significant uranium deposits like Germany, the United States, and the Czech Republic.
A small UV light source is included with the purchase.
