Locality type:


Carbonatite complex (calcite carbonatites and nephelinites) hosted in quartzite.

The quartz crystals of the quartzite show numerous solid microinclusions of halides and carbonates precipitated from pristine hydrous carbonate melts (carbonatite-derived fluid trapped under closed-system conditions).
