Glauconite - an overview | ScienceDirect Topics

The glauconite appears to be gradually changed to a mixed-layer mineral with less potassium (glauconite mica) until the oxide-kaolinite stage is reached. The evolution in carbonates would be a sort of ‘reverse’ weathering, which arrives gradually in an alkali-free assemblage, whereas in sandstones the alteration is made, apparently, in one step with the formation of kaolinite and

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.
