... ). According to its cell parameters, vicanite-(Ce) is closely related to okanoganite ( Boggs 1980 ), a REE borofluorosilicate from Okanogan County, Washington. Two different crystals from the same locality were used for crystallographic study at Pavia ( a ) and Rome ( b ). Crystal a represents...
