Zirconolite

Formula:
CaZrTi
 
2
O
 
7
Colour:Black to brown, redHardness:


A complex zirconium titanium silicate with three polytypoids known (2M, 3O, 3T).

Gieré et al. (1998) identified five hypothetical end-members, CaZrTi2O7, CaZrMe5+Me3+O7, ACTZrTiMe2+O7, REEZrTiMe3+O7 and REEZrMe5+Me2+O7.
The last one has been observed as a 53% percentage of REEZrNb(Mn,Fe)O7 in a sample from the Eifel volcanic region (Della Ventura et al., 2000).
