We are trying to decipher origin of magnetite-apatite ores from Evate deposit, Mozambique. I would like to know if someone observed textures like that illustrated in the attached figure, showing oval baddeleyite crystal decorated by euhedral spinels, all enclosed in magnetite with geikielite exsolution lamellae. Note that smaller euhedral spinels are regularly distributed in the magnetite, except for spinel free-zone around the baddeleyite grain. In our opinion, this may indicate the spinel growth controlled by the Ostwald ripening, i.e. dissolution of small crystals and their redeposition on the surfaces of larger crystals and nucleation centers. This interpretation is supported by the intersection of some spinel grains by geikielite exsolution lamellae, thus suggesting the spinel growth taking place in Fe-oxide melt. I would be grateful for some alternative interpretations (solid state diffusion?), including references to published works describing similar phenomenon.
