Some rock types containing chlorite, such as chlorite schist, have minor decorative uses or as construction stone. However, chlorite is a common mineral in clay, which has a vast number of uses. [9] Chlorite schist has been used as roofing granules, the mineral granules adhered to asphalt composition shingles due to the green color.
Selenium, which is an essential element for animals and prokaryotes and is a beneficial element for many plants, is the least-common of all the elements essential to life.

[14] Lineated schist has a strong linear fabric in a rock which otherwise has well-developed schistosity. [10]
The "seed" method uses grains of ground shell from freshwater mussels, and overharvesting for this purpose has endangered several freshwater mussel species in the southeastern United States. [5] The pearl industry is so important in some areas, significant sums of money are spent on monitoring the health of farmed molluscs. [6]

Chlorite schist, a type of greenschist Greenschist (prasinite) at Cap Corse in Corsica, France Greenschist (epidote) from Itogon, Benguet, Philippines. Greenschists are metamorphic rocks that formed under the lowest temperatures and pressures usually produced by regional metamorphism, typically 300–450 °C (570–840 °F) and 2–10 kilobars (29,000–145,000 psi).
