Hypersthene is a common rock-forming inosilicate mineral belonging to the group of orthorhombic pyroxenes.
 Many references have formally abandoned this term, preferring to categorise this mineral as enstatite or ferrosilite.
 It is found in igneous and some metamorphic rocks as well as in stony and iron meteorites.
 It forms a solid solution series with the minerals enstatite and ferrosilite, being a mid-way member between the two.
 Pure enstatite contains no iron, while pure ferrosillite contains no magnesium; hypersthene is the name given to the mineral when a significant amount of both elements are present.
 The chemical formula is (Mg,Fe)SiO.
Leucophanite is an inosilicate mineral with a complex composition, (Na,Ca)BeSi(O.OH.F).
 It may contain cerium substituting in the calcium position.
Babingtonite is a calcium iron manganese inosilicate mineral with the formula Ca(Fe,Mn)FeSiO(OH).
 It is unusual in that iron(III) completely replaces the aluminium so typical of silicate minerals.
 It is a very dark green to black translucent (in thin crystals or splinters) mineral crystallizing in the triclinic system with typically radial short prismatic clusters and druzy coatings.
 It occurs with zeolite minerals in cavities in volcanic rocks. Babingtonite contains both iron(II) and iron(III) and shows weak magnetism.
 It has a Mohs hardness of 5.5 to 6 and a specific gravity of 3.3.
Bustamite is a calcium manganese inosilicate (chain silicate) and a member of the wollastonite group.
 Magnesium, zinc and iron are common impurities substituting for manganese.
 Bustamite is the high-temperature polymorph of CaMnSiO and johannsenite is the low temperature polymorph.
 The inversion takes place at 830 C , but may be very slow.Bustamite could be confused with light-colored rhodonite or pyroxmangite, but both these minerals are biaxial (+) whereas bustamite is biaxial (-).
Diorite ( ) is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and/or pyroxene.
 The chemical composition of diorite is intermediate, between that of mafic gabbro and felsic granite.
 Diorite is usually grey to dark-grey in colour, but it can also be black or bluish-grey, and frequently has a greenish cast.
 It is distinguished from gabbro on the basis of the composition of the plagioclase species; the plagioclase in diorite is richer in sodium and poorer in calcium.
 Diorite may contain small amounts of quartz, microcline, and olivine.
 Zircon, apatite, titanite, magnetite, ilmenite, and sulfides occur as accessory minerals.
 Minor amounts of muscovite may also be present.
 Varieties deficient in hornblende and other dark minerals are called "leucodiorite".
 When olivine and more iron-rich augite are present, the rock grades into "ferrodiorite", which is transitional to gabbro.
 The presence of significant quartz makes the rock type "quartz-diorite" (>5% quartz) or tonalite (>20% quartz), and if orthoclase (potassium feldspar) is present at greater than 10 percent, the rock type grades into "monzodiorite" or granodiorite.
 A dioritic rock containing feldspathoid mineral/s and no quartz is termed "foid-bearing diorite" or "foid diorite" according to content.
William Hyde Wollaston {'1': ", '2': ", '3': ", '4': "} ( ; 6 August 1766 – 22 December 1828) was an English chemist and physicist who is famous for discovering the chemical elements palladium and rhodium.
 He also developed a way to process platinum ore into malleable ingots.
Ankerite is a calcium, iron, magnesium, manganese carbonate mineral of the group of rhombohedral carbonates with formula: Ca(Fe,Mg,Mn)(CO).
 In composition it is closely related to dolomite, but differs from this in having magnesium replaced by varying amounts of iron(II) and manganese.
 It forms a series with dolomite and kutnohorite.
The pyroxenes (commonly abbreviated to "Px") are a group of important rock-forming inosilicate minerals found in many igneous and metamorphic rocks.
 Pyroxenes are silicon-aluminum oxides with Ca, Na, Fe, Mg, Zn, Mn, Li substituting for Si and Al.
 The general formula is XY(Si,Al)O (where X represents calcium, sodium, iron and magnesium and more rarely zinc, manganese and lithium and
Vivianite (Fe2+Fe2+2(PO4)2·8H2O ) is a hydrated iron phosphate mineral found in a number of geological environments.
 Small amounts of manganese Mn, magnesium Mg and calcium Ca may substitute for iron Fe in the structure.
 Pure vivianite is colorless, but the mineral oxidizes very easily, changing the color, and it is usually found as deep blue to deep bluish green prismatic to flattened crystals.
Wollastonite is a calcium inosilicate mineral (CaSiO) that may contain small amounts of iron, magnesium, and manganese substituting for calcium.
 It is usually white.
 It forms when impure limestone or dolostone is subjected to high temperature and pressure sometimes in the presence of silica-bearing fluids as in skarns or contact metamorphic rocks.
 Associated minerals include garnets, vesuvianite, diopside, tremolite, epidote, plagioclase feldspar, pyroxene and calcite.
 It is named after the English chemist and mineralogist William Hyde Wollaston (1766–1828).
