Micro crystals in small gas amygdales in a permian rhombic porphyrhy lava (Flow RP2b) near the lake Sandungen.
Note to mineralist:
Intimate syntactic intergrowths of polycrystals of parisite and synchysite has been reported from this locality, and the species are probably parisite-(Ce) and synchysite-(Ce) (not confirmed).
