'Allanite Group'
Formula: {A12+REE3+}{M3+2M32+}(Si2O7)(SiO4)O(OH)
Reference: Ontario Ministry of Northern Development and Mines MDI Number: MDI31D15SE00116
Formula: C
Reference: Ontario Ministry of Northern Development and Mines MDI Number: MDI31D15SE00116
Formula: (Ca,Na,U,□)2(Nb,Ti)2O6(OH)
Reference: Hogarth, D. (1961) A Study of Pyrochlore and Betafite, Canadian Mineralogist, v. 6, p. 610-633.
Formula: Fe2+Fe3+2O4
Reference: Ontario Ministry of Northern Development and Mines MDI Number: MDI31D15SE00116
Formula: Ca2(Ti,Nb)2O6O
Description: Chemical analysis by Hogarth (1961) suggested the mineral from this location was "betafite", but the specimens are too ti-poor to be oxycalciobetafite. The analysis indicates hydroxycalciopyrochlore.
