Segelerite



Segelerite is a complex phosphate mineral with formula CaMgFe3+OH(PO4)2·H2O. It occurs in pegmatites and forms striking green or chartreuse crystals. It was discovered in 1974 in the Black Hills of South Dakota by an amateur mineralogist from New York, Curt G. Segeler (1901-1989), after whom it is named.

Additional recommended knowledge

It is closely related to overite which is virtually the same mineral except that the iron is replaced by aluminium. Another mineral in the same series is juonniite wherein the iron is also replaced, this time by scandium.
