Kyanite is a typically blue aluminosilicate mineral, found in aluminium-rich metamorphic pegmatites and sedimentary rock. It is the high pressure polymorph of andalusite and sillimanite , and the presence of kyanite in metamorphic rocks generally indicates metamorphism deep in the Earth's crust .
Mineral symbols (text abbreviations) are used to abbreviate mineral groups, subgroups, and species, just as lettered symbols are used for the chemical elements.. The first set of commonly used mineral symbols was published in 1983 and covered the common rock-forming minerals using 192 two- or three-lettered symbols. [1]
Kainite (/ ˈ k aɪ n aɪ t / or / ˈ k eɪ n aɪ t /) [4] (KMg(SO 4)Cl·3H 2 O) is an evaporite mineral in the class of "Sulfates (selenates, etc.) with additional anions, with H 2 O" according to the Nickel–Strunz classification.
The minerals kyanite and sillimanite are polymorphs of andalusite, each occurring under different temperature-pressure regimes and are therefore rarely found together in the same rock. Because of this the three minerals are a useful tool to help identify the pressure-temperature paths of the host rock in which they are found.

It is helpful to be able to understand the source of scientific names. Although the Latin names do not always correspond to the current English common names, they are often related, and if their meanings are understood, they are easier to recall. The binomial name often reflects limited knowledge or hearsay about a species at the time it was named.
Omphacite is a member of the clinopyroxene group of silicate minerals with formula: (Ca, Na)(Mg, Fe 2+, Al)Si 2 O 6.It is a variably deep to pale green or nearly colorless variety of clinopyroxene.
The name eclogite is derived from the Ancient Greek word for 'choice' (εκλογή, eklogḗ), meaning 'chosen rock' on account of its perceived beauty. It was first named by René Just Haüy in 1822 in the second edition of his work Traité de minéralogie. [1]
