www.sciencedirect.com/science/article/pii/S0272884218312951Zirconolite is considered to be an anion-deficient derivative of fluorite structure type with five polytypic forms, including zirconolite-2M (monoclinic, C2/c) , zirconolite-4M (monoclinic, C2/c) , zirconolite-3T (trigonal, P312) , , zirconolite-3O (orthorhombic, Acam) and zirconolite-6T (trigonal, P312) .Zirconolite-2M is the most studied structure to immobilize actinides among these polytypes.
en.wikipedia.org/wiki/Oxide_mineralThe oxide mineral class includes those minerals in which the oxide anion (O 2−) is bonded to one or more metal alloys. The hydroxide-bearing minerals are typically included in the oxide class.The minerals with complex anion groups such as the silicates, sulfates, carbonates and phosphates are classed separately.. Simple oxides: X 2 O and XO . Cuprite Cu 2 O; Ice H 2 O ...
