MoreTombarthite is a hydrohydroxysilicate of rare earths. It is found in one of the Precambrian granite pegmatite dykes in the Iveland-Evje area, South Norway. It has a monazite type structure with a=7.12 , b=7.27 , c=6.70 , β=102°30′ (average of two samples). The generalized formula is RE 4 (Si+4H) 4 O 12−n OH 4 +2n, where O≦n≦4.
