The presence of crinoid fragments indicates an unequivocal marine origin for these sediments, and this is strongly supported by the presence of bioturbation and glauconite. Formation by marine and littoral processes is inferred from marine fossils, glauconite and sedimentary features in the basal sedimentary cover. Some striking images of stromatolitic textures complement a chapter on desert varnishes, and there is extensive treatment of textures revealing growth histories in glauconite. The upper part of the unit contains some green clay which can probably regarded as altered glauconite. These sediments also contain glauconite, which occurs as isolated and agglutinated pellets up to 1 mm across. The glauconite is often seen in close association with crystals of sedimentary pyrite. Glauconite is present in silty mudstone near the base of the member as agglutinated pellets up to 2 mm across. Overlying transgressive marine sediments (c) comprise sands and silts containing first-cycle schist clasts and re-worked fluvial sediment (basal) overlain by silts containing glauconite (g) and occasional molluscan fossils. The iron rich member of the illite group, glauconite, in sediments can be differentiated by x-ray analysis. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These vary from fossil bearing sandy clays to sands, clays, and carbonate beds absent of fossil content with glauconite and phosphate mica which is common.

The deposits are found mostly in the blue earth glauconite, a layer 1 to 17.5 meters thick found 25 to 40 meters from the surface.

These grains are called "glauconies" and consist of a mixture of mixed-layer clay minerals, such as smectite and glauconite mica.

Greensands are green because of iron-bearing glauconite which is usually recognized as illite/mica or mixed layer illite-smectite clay by x-ray diffraction.
