Glauconite - Wikipedia
Glauconite is an iron potassium phyllosilicate (mica group) mineral of characteristic green color which is very friable [5] and has very low weathering resistance. It crystallizes with a monoclinic geometry.

glauconite, greenish ferric-iron silicate mineral with micaceous structure [ (K, Na) (Fe 3+,Al, Mg) 2 (Si, Al) 4 O 10 (ΟH) 2], characteristically formed on submarine elevations ranging in depth from 30 to 1,000 metres (100 to 3,300 feet) below sea level.
Glauconite: Mineral information, data and localities. - mindat.org
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).

Glauconite (series) - Ohio Department of Natural Resources
Glauconite ((K,Na)(Fe,Mg,Al) 2 (SiAl) 4 O 10 (OH) 2) is a silicate mineral series that is characteristically green in color and has a very low weathering resistance. This mineral is rich in potassium and is therefore used as a potassium fertilizer source in agriculture.
Glauconite - an overview | ScienceDirect Topics
Glauconite is an authigenic mineral that forms through the transition of clay minerals in the sea or by direct precipitation from seawater. It is commonly found in shallow marine environments and is characterized by its rounded shape, dark green color, and high potassium content.

Glauconite - Sandatlas
Glauconite is a green-colored mineral. It is structurally similar to micas and is sometimes considered to be one of the mica minerals. Despite that it appears usually in rounded ill-formed platelets which are not at all similar to typical flakes of common micas like muscovite and biotite.
