Feo In Silica Sand

Glauconite: Mineral information, data and localities.

Named in 1828 by Christian Keferstein from the Greek "glaukos," blue-green, in allusion to its color; but the term "glauconie" was used earlier, in 1823 by Alexandre Brongniart, as a name for the English term "green sand". Both celadonite and glauconite were lumped with grünerde, the approximate German equivalent of green sand, by Dana (1844).
