what is glauconite mineral

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.

Greenish sand-sized grains described as ‘glauconite’ are usually mixtures of minerals rather than single mineral species (Burst, 1958 a; 1958 b), although a constituent common in such grains is the mineral glauconite, a hydrated iron-rich micaeous clay mineral of the illite group (K Mg (Fe, Al) (SiO 3) 6.3H 2 O).

Glauconite - NASA/ADS

The term glauconite has been employed in two senses. It has been used most commonly as a morphological term for sand-sized greenish grains found in sedimentary rocks, but also as a name for a specific mineral species, a hydrated iron-rich micaceous clay mineral. The two uses are not synonymous, since not all morphological glauconite consists exclusively of mineral glauconite, nor is the latter ...

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 ...
