Hydroxylbastnäsite-(La)

Formula:
(La,Ce)[(OH,F)|CO
 
3
]
System:HexagonalColour:Yellow
Hardness:4
Name:For the locality at the Bastnäs mines, Riddarhyttan, Skinnskatteberg, Västmanland, Sweden, plus the "Hydroxyl" prefix due to the dominance of the hydroxyl radical over fluorine and the "-(La)" suffix due to the dominance of lanthanum in the composition.


The hydroxyl analogue of Bastnäsite-(La); the lanthanum analogue of Hydroxylbastnäsite-(Ce) and Hydroxylbastnäsite-(Nd).

Originally reported from Nissi bauxite deposit, Lokris, Fthiótis Prefecture, Sterea Hellas Department, Greece.
