“SEM image in back-scattered electrons. Analyzed particle of dark brown the yearlier Laverovite with marked points of analyses. Point #2 belongs to Zirconian Kupletskite with small octahedral cations in formula (Ti1.04Zr0.88Nb0.08)2.00. Points #1, 3, 4 and 5 are belongs to Titanian Laverovite with compositions (Zr1.08Ti0.86Nb0.06)2.00, (Zr1.02Ti0.91Nb0.07)2.00, (Zr1.00Ti0.95Nb0.05)2.00 and (Zr0.95Ti0.84Nb0.21)2.00.
Points #6, 7 and 8 belongs to light-pink fibrous UN close compositionally to Niobokupletskite, but much more rich by manganese (about 1.5 times).
The small brightmost octahedral crystals intergrown with this UK are represented by Hydroxymanganopyrochlore-like or Peterandresenite-like cubic phase.
Analytical data are available at daughter photos.
