chlorite ¹  (klôrt)

A usually green or black, flaky mineral that looks like mica. Chlorite is either monoclinic or triclinic and occurs in low-grade metamorphic rocks (rocks that have undergone little metamorphism). It often forms by the alteration of dark minerals (often rich in iron and magnesium) during metamorphism. Chemical formula: (Mg,Fe,Al)₆(Si,Al)₄O₁₀(OH)₈.

chlorite ²  (klôrt)

A salt containing the group ClO₂.
