Retzian-(Ce)
Moore P B
American Mineralogist 52 (1967) 1603-1613
Crystal chemistry of the basic manganese arsenate minerals 1. The crystal
structures of flinkite, Mn2Mn(OH)4(AsO4) and retzian, Mn2Y(OH)4(AsO4)
Note: Moore did not determine the REE compostion of the sample.
Subsequent work by Dunn & Sturman (1982) concluded that it is Ce dominant
Consequently, the REE in this structure has been changed to Ce
