What is Anzaite-(ce)?
Anzaite-(Ce) is a rare-earth element (REE) oxide mineral with the formula Ce4FeTi6O18(OH)2. An example of chemically related mineral is lucasite-(Ce), although it contains no iron. Cerium in anzaite-(Ce) is mainly substituted by neodymium, lanthanum, calcium and praseodymium. Titanium is substituted by niobium. Trace elements include thorium. The mineral is monoclinic, space group C2/m. Anzaite-(Ce) is hydrothermal mineral found in a carbonatite from the mineralogically-prolific Kola Peninsula. The mineral name honors Anatoly N. Zaitsev, who is known for studies of carbonatites and REE.

Key Characteristics
Formation of Anzaite-(ce)
Parent rocks for anzaite-(Ce) are silicocarbonatites of the Afrikanda alkali-ultramafic massif. These rocks underwent hydrothermal reworking, that beside anzaite-(Ce) produced also calcite, clinochlore, hibschite and titanite in expense of primary minerals.
Composition of Anzaite-(ce)
The crystal structure of anzaite-(Ce) characterizes in: the presence of layers with REE (square antiprismatic coordination) and Fe (octahedral) the presence of layers with Ti with coordination numbers 5 and 6 disorder of Fe, Ti and two of four present anion sites The disordered sites are located on the (010) planes, separated by ordered domains containing REE, Ti (octahedral) and two oxide-anion sites.
