Spectroscopic analysis: <1% Ca, Si; <0.1% Al, Mg; <0.01% Ag, B, Ba, Fe, Ti; <0.001% Mn, Pb, Sn.
Pattern taken at 26 C.
Opaque mineral optical data on specimen from Liskeard, Cornwall, England, UK.
Pattern reviewed by Martin, K., McCarthy, G., North Dakota State Univ., Fargo, North Dakota, USA, ICDD Grant-in-Aid (1990).
Agrees well with experimental and calculated patterns.
Additional weak reflection [indicated by brackets] was observed.
