FAQ
Frequently Asked Questions
No. Chloride (Cl−) is a single ion of chlorine. Chlorite (ClO2−) is a compound ion containing chlorine and oxygen. They are chemically distinct.
In geology, chlorite is often found in metamorphic rocks like schists and phyllites, and as an alteration product of minerals like biotite and pyroxene.
The mineral form is generally inert. The chemical form (e.g., sodium chlorite) can be hazardous, reactive, and used in controlled industrial processes like bleaching.
It helps geologists determine the pressure and temperature conditions (metamorphic grade) the rock experienced, as chlorite forms under specific low-grade conditions.
A green mineral consisting of a hydrous silicate of aluminium, iron, and magnesium.
Chlorite is usually academic/technical (primarily geology, mineralogy, chemistry) in register.
Chlorite: in British English it is pronounced /ˈklɔːrʌɪt/, and in American English it is pronounced /ˈklɔːraɪt/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Think 'CHLORe' (as in chlorine/chlorophyll, both green) + 'ITE' (common ending for minerals/rocks). It's a green mineral.
