Glauconite, greenish ferric-iron silicate mineral with micaceous structure [(K, Na)(Fe3+,Al, Mg)2(Si, Al)4O10(ΟH)2], characteristically formed on submarine elevations ranging in depth from 30 to 1,000 metres (100 to 3,300 feet) below sea level. Glauconite is abundant only in sea-floor areas that

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 iron oxide.
Abstract 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
Glauconite is a mineral consisting of hydrous silicates of iron and potassium. Glauconite is dull green in color. It has the consistency and feel of chalk; it breaks apart very easily upon contact. Glauconite is commonly found in sandstone and limestone and is a member of the mica group of minerals.
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. However, it still possesses perfect cleavage like other micas, we just don’t see it. Sometimes it is

Description. Grossièrement cristalline, la glauconite est généralement terreuse, ressemblant à de la chlorite, elle aussi verdâtre. Aspect : Opaque. Éclat mat. Couleur : Glauque, vert jaunâtre, vert olive à vert noirâtre (poussière verdâtre).. Formation. C’est un minéral d’altération diagénétique de la biotite ou de verre volcanique se formant en milieu marin peu profond, à
Illite is a group of closely related non-expanding clay minerals. Illite is a secondary mineral precipitate, and an example of a phyllosilicate, or layered alumino-silicate.Its structure is a 2:1 sandwich of silica tetrahedron (T) alumina octahedron (O) silica tetrahedron (T) layers. The space between this T-O-T sequence of layers is occupied by poorly hydrated potassium cations which
Glauconite definition is a mineral consisting of a dull green earthy iron potassium silicate occurring in greensand.

The technologies for use of glauconite as a fertiliser have been developed on the following two routes: Beneficiation / Concentration of the mineral to make it viable for use as fertiliser. Lab scale technology has been reported to be developed by RRL Bhopal and some work done by others. Second route is to process the glauconite with some additives to make easy availability of low
