System:MonoclinicColour:Blue-green, ...
Hardness:2
Name:Named in 1828 from the Greek "glaukos," blue-green, in allusion to its color; but the term "glauconie" was used earlier, in 1823.


Typically found as rounded aggregates or "pellets" of very fine grained scaly particles, having a blue-green to yellow-green color.

Classification of Glauconite

IMA status:Valid - first described prior to 1959 (pre-IMA) - "Grandfathered"
Explanation of status:The name is for a series in the Mica Group, not an individual species. While it is currently accepted, it is likely that once the species in the series have been better defined it will be replaced by two or more species names.

Occurrences of Glauconite

Geological Setting:Formed in shallow marine environments that are mildly reducing when little or no sedimentation is taking place, hence found in shallow marine sedimentary rocks - limestones, siltstones, shales and sandstones. "Greenstones" are named that because if their typically high glauconite content.
