- 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.
- A salt containing the group ClO2.
