Zirkelite from the Sebl'yavr carbonatite complex, Kola Peninsula, Russia; an X-ray and electron microprobe study of a partially metamict mineral -- Bulakh et al.
Zirkelite, a cubic mineral of general formula (Ti, Ca, Zr)O (sub 2-x) occurs as an accessory mineral in phoscorites, carbonatites and associated rocks in the Sebl'yavr complex.
Zirkelite forms platy crystals comprising polysynthetic octahedral twins, often having a complex skeletal internal structure within a cuboctahedral external morphology.

Calzirtite, zirkelite, zirconolite, baddeleyite and zircon are primary minerals of Ti and Zr in carbonatites.
The trends of the alteration of titanium and zirconium minerals: perovskite - baddeleyite - zirconolite, calzirtite - zirkelite - pyrochlore, zirconolite - pyrochlore (Bulakh, 1996), baddeleyite (and uranpyrochlore) - zirconolite - zircon and zircon - baddeleyite (Kapustin, 1964) were described previously.
According to our data, zircon forms partial or complete pseudomorphs on the calzirtite in zones of hydrothermal alteration at the contact between the carbonatites and pyroxenites of the Seblyavr massif (Kola Peninsula, Russia).
