[(K,Na,Ca) 1.2-2.0 (Fe +3,Al,Fe +2,Mg) 4 (Si 7-7.6 Al 1-0.4 O 20)(OH) 4 7nH 2 0] A green silicate mineral found in sedimentary rocks and formed on continental shelves characterized by slow sedimentation and organic matter, such as fecal pellets, present in an oxidizing environment. In sufficient quantity, it can form a sandy, green deposit such as the Cretaceous greensands of the US and UK.
Mariposite. Mariposite forms in metamorphasized Dolomite and Quartz, and these are usually present as veins or as a base material. A combination of the green mica and the veins or base material forms a rock which is also called Mariposite, and it is sometimes used as an ornamental stone.
Aug 30, 2019· Glauconite is a mineral in the mica group — a sheet-like, silicate mineral with that weathers quickly.
Abstract. Glauconite is the only clay material occurring in sedimentary rocks which is known to be authigenic in origin, is abundant, and is relatively free from impurities. Thus the geochemistry of glauconite should be a fruitful area of study. At present, most of the emphasis has been restricted to age-dating aspects,...

Glauconite is typical marine clay mineral formed in characteristic environmental conditions in shallow seas. Glaukonite ores in the eastern part of European continent was deposited millions of years ago when Europe was still under water, the rocks formed sheltered .
Species: GLAUCONITE Locality: Government Pit, Albany, NH Specimen Size: 7 cm specimen. Green Glauconite coating on Microcline and smoky quartz. Field Collected: Tom Mortimer Catalog No.: 1289 Notes: This specimen was previously believed to be an example of New Hampshire nontronite. The specimen has the appearance of what collectors have thought to be nontronite-chloropal.
In a few places a red colour prevails, the iron being mostly oxidized; elsewhere the muds are green owing to abundant glauconite. 0 Greensand is a mineral that .
Definition of ''glauconite''. glauconite in British. a green mineral consisting of the hydrated silicate of iron, potassium, aluminium, and magnesium: found in greensand and other similar rocks.
Glaucony is a greenish grain which belongs to the glauconite mineral family, and which forms inside shells (often foraminifer tests) or pellets or biotite sheets (McRae, 1972;Odin, 1988;Giresse ...
Greensand is a mineral that contains an iron-potassium silicate known as glauconite. Green mud differs to a greater extent from the blue mud, and owes its characteristic nature and colour to the presence of glauconite, which is formed inside the cases of foraminifera, the spines of echini and the spicules of sponges in a manner not yet understood.

Glauconite is a mineral for our future. It is a green attractive mineral which in massive accumulations forms rocks called greensands. It is of interest to indu ... stry because it contains potassium, the K in the N-P-K of fertilizers and essential for all plant life.
Glauconite is an iron potassium phyllosilicate (mica group) mineral of characteristic green color with very low weathering resistance and very friable. It crystallizes with a monoclinic geometry. Its name is derived from the Greek glaucos ( γλαυκος ) meaning ''gleaming'' or ''silvery'', to describe the appearance of the blue-green color, presumably relating to the sheen and blue-green color of the sea''s surface.
Mariposite. Mariposite forms in metamorphasized Dolomite and Quartz, and these are usually present as veins or as a base material. A combination of the green mica and the veins or base material forms a rock which is also called Mariposite, and it is sometimes used as an ornamental stone.
Glauconite is a bright green mineral that looks like tiny flakes of the mineral mica, or small lumps of clay. The color of glauconite varies considerably from pale green, bright green, bluish-green, olive-green, and black-green, depending upon its constituent elements.
Petrological analysis revealed a high proportion of a porous clay mineral, glauconite. The glauconite was distributed as pellets with high internal, water-bearing porosity. These pellets were randomly distributed throughout the matrix and were shown to be strongly water wet.
Glauconite is a complex mineral composed mainly of iron, potassium, and magnesium hydrated aluminum silicates. Due to its complex mineralogy in particular variations in iron content, it has a wide range of grain densities.
