Glauconite: Mineral information, data and localities.

Glauconites are dioctahedral interlayer-deficient micas (as are illite s). Typically found as rounded aggregates or "pellets" of very fine grained scaly particles, having a blue-green to yellow-green color. True glauconites may have been found in other environments, but, before 1998, may have been classed as

Mineral glauconite in sensu lato is a random interstratification of nonexpanding 10A˚layers and expanding montmorillonitic layers. The amount of expandable layers may be over 50 % but it is customary to restrict the name mineral glauconite in sensu stricto to varieties with less than 10 % expandable layers.

1975-8-1  The mineral in monomineralic glauconite pellets is an iron-rich mixed-layer illite-smectite (here called glauconite), often composed almost entirely of illite layers. The nature of the interlayering is closely analagous to that of aluminous illite-smectite and varies with the proportions of the layer types: >30 per cent smectite, randomly interstratified; 15–30 per cent smectite, allevardite ...

2021-5-14  Greensand is composed primarily of the mineral glauconite -- a potassium, iron, aluminum silicate. In some Delaware greensands, the glauconite content exceeds 90%. The remaining 10% is mainly quartz. In the past, greensand was used in Delaware as an inexpensive fertilizer. The only active greensand mine in the U.S. today is in New Jersey. Once mined, greensand is dried and used as a

Glauconite pellets are deemed to result from a variety of origins that require the three-layer silicate lattice, supplies of potassium and iron, and a suitable oxidation potential for transformation. Variations in these three fundamental requirements are believed responsible for the pellet variations.
