Baddeleyite ZrO2 is identifed in abundant assemblages with zircon in alkali pegmatites of the Vishnevogorsky complex. the mineral contains Hf, Nb, and Ca in chemical composition. Its occurrence in form of accessory mineral is predicted for various rocks and pegmatite bodies of the Vishnevogorsko-ilmenogorsky alkaline complex.
