Chlorite minerals show a wide variety of compositions, in which magnesium, iron, aluminium, and silicon substitute for each other in the crystal structure. A complete solid solution series exists between the two most common end members, magnesium-rich clinochlore and iron-rich chamosite. In addition, manganese, zinc, lithium, and calcium ...
Seraphinite is a trade name for a particular form of clinochlore, a member of the chlorite group. Seraphinite; Seraphinite specimen. General; Category: Seraphinite ...
This list includes those recognised minerals beginning with the letter C.The International Mineralogical Association is the international group that recognises new minerals and new mineral names; however, minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.
Chamosite is the Fe 2+ end member of the chlorite group.A hydrous aluminium silicate of iron, which is produced in an environment of low-to-moderate-grade metamorphosed iron deposits, as gray or black crystals in oolitic iron ore.
Cummingtonite is commonly found in metamorphosed magnesium-rich rocks and occurs in amphibolites. Usually it coexists with hornblende or actinolite, magnesium clinochlore chlorite, talc, serpentine-antigorite minerals or metamorphic pyroxene. Magnesium-rich cummingtonite can also coexist with anthophyllite.
Cookeite is a mineral species of the silicate group and the phyllosilicate subgroup, part of the chlorite family, with the formula LiAl 4 (Si 3 Al)O 10 (OH) 8. [1] This soft, low-density mineral of variable color has a crystalline structure made up of alternating layers LiAl 2 (OH) 6 and Al 2 O 4 (OH) 2 Si 8 O 12 having several polytypes.
Parent rocks for anzaite-(Ce) are silicocarbonatites of the Afrikanda alkali-ultramafic massif. These rocks underwent hydrothermal reworking, that beside anzaite-(Ce) produced also calcite, clinochlore, hibschite and titanite in expense of primary minerals. [2]
Actinolite is commonly found in metamorphic rocks, such as contact aureoles surrounding cooled intrusive igneous rocks.It also occurs as a product of metamorphism of magnesium-rich limestones.
