Leucophanite

Leucophanite

Leucophanite is a sorosilicate mineral with a complex composition, (Na,Ca)2BeSi2(O.OH.F)7. It may contain cerium substituting in the calcium position.

It occurs in pegmatites and alkali igneous complexes as yellow, greenish or white triclinic crystals and has been found in Norway, Quebec and Russia.

It was first described from the Langesundfiord district of southern Norway in 1840. The name is from the Greek "leucos" for "white" and "phanein" for "to appear" in allusion to the common white color.
