Etymology: < the name of Anders Jahan Retzius (1742–1821), Swedish naturalist + -an suffix. Compare Swedish retzian (H. Sjögren 1897, in Geologiska Föreningens i Stockholm Förhandlingar 19 106).

Mineralogy.

A rare manganese-containing mineral which occurs as dark brown prismatic or tabular crystals.Retzian is an arsenate and hydroxide of manganese and cerium (sometimes with other rare earth elements), Mn₂(Ce, La, Nd)AsO₄(OH)₄. Crystal system: orthorhombic.In more recent use often with following chemical symbol, indicating the predominant rare earth element present, as retzian-(Ce) (cerium), retzian-(La) (lanthanum), and retzian-(Nd) (neodymium).
