    www.sciencedirect.com/science/article/pii/S0022459603002226 The atomic coordinate changes from weberite-3T to zirconolite-3T are accompanied by a large contraction in the c-axis of zirconolite relative to weberite, given in Table 1. Relative to the parent cubic fluorite structure, zirconolite-3T undergoes a strong contraction along one of the {111} fluorite axes (c/√2a=1.644

Zirconolite-2M is the stable polytype for the pure CaZrTi 2 O 7 end member. Zirconolite crystallography is complex, with five polytypes identified, formed from different stacking patterns of a common hexagonal tungsten bronze motif.

    en.wikipedia.org/wiki/Oxide_minerals The 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..
