Olá friends !!!!
I've been to see the magazine article of Mineralogical Record 37/1 about Francon quarry minerals and could not identify the white crystals with a octahedral configuration. Someone expert on the mineralogy of this site can help me identify this mineral.
Thanks.... Martins da Pedra

Maybe a pseudomorphose of Cryolite in Gibbsite ?
Thanks

The cryolite is pale yellow, and with well defined edges. These white crystals are rounded, but realizes the octahedral configuration. Yes it can be Fluorite but the Fluorite of this place is lilac....well is strange and is not mentioned or photographed in the magazine article.
