Autunite - Wikipedia Autunite (hydrated calcium uranyl phosphate), with formula Ca(UO 2) 2 (PO 4) 2 ·10–12H 2 O, is a yellow-greenish fluorescent phosphate mineral with a hardness of 2– 2 + 1 ⁄ 2 [4] [5] Autunite crystallizes in the orthorhombic system and often occurs as tabular square crystals, commonly in small crusts or in fan-like
Autunite | Physical - Optical Properties, Occurrence, Uses More Autunite is a phosphate mineral that formula is calcium uranium phosphate (Ca (UO2)2(PO4)2·10–12H2O) and It is harness of 2 – 2, 5 A popular collector’s mineral Greenish or lemon yellow in color, autunite specimens fluoresce green under ultraviolet light
Autunite: Properties, Occurrence, Uses – Geology In Autunite is a hydrated calcium uranyl phosphate mineral with the chemical formula Ca(UO₂)₂(PO₄)₂·10–12H₂O Autunite is a product of the alteration of uraninite It is the most common surface uranium mineral, abundant in the oxidation zones of uranium deposits ; it is also found more rarely in pegmatitic veins containing uranium and
Autunite | Radioactive, Phosphate, Uranium | Britannica autunite, phosphate mineral, hydrated calcium and uranium phosphate [Ca(UO 2) 2 (PO 4) 2 ·10–12H 2 O], that is an ore of uranium It forms translucent to transparent, yellow to pale-green crystals, scaly masses, or crusts in hydrothermal veins and pegmatites, where it occurs as an alteration product of uraninite
