About Glauconite

Lustre:
Dull, Earthy

Name:
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). Eventually, glauconite was applied just to the sedimentary pellets, with which the species has been tied ever since, although the celadonites were essentially lumped together until the new species of the celadonite sub-group were established in 1997 by Gejing Li, Donald Ralph Peacor, Douglas S. Coombs, and Yosuke Kawachi. Rieder et al. (1998) kept glauconite as a compositional space ("series") for interlayer-deficient, Fe+/-Mg-rich dioctahedral micas, the analog of illite and related to the celadonite subgroup.
First Recorded Locality:
Not an IMA-approved name.
This mineral has long been described in the literature and recognised by most geologists but is not easily defined. The green "glaucony" mineral commonly found in marine sediments has been defined as a mixed-layer glauconite-smectite (Odin & Létolle, 1980) but in part it can actually be a mixture of minerals from the mica, serpentine and chlorite groups, rather than a pure glauconite mineral.
Rieder et al. (1998) defined Glauconites somewhat vaguely as a counterpart of illite, as dioctahedral interlayer-deficient (i.e. (K+Na)<0.85) micas with (Mg+Fe)>Al and Fe3+ > Al in the octahedral sites (basically being interlayer deficient celadonite subgroup minerals). The range of interlayer cation site occupancy is defined as 0.6-0.85; in the octahedral layer (Mg+Fe)>Al. It could be a subgroup with members defined similar to the celadonite subgroup, or just represent varieties of the celadonite subgroup.
Typically found as rounded aggregates or "pellets" of very fine grained scaly clay particles, having a blue-green to yellow-green or grey-green color. True glauconites may have been found in other environments (e.g. igneous rocks), but, before 1998, may have been classed as celadonite.
