Name:
Named in 1851 by William Phipps Blake from the Greek κλινειν "klinein", "to incline", in allusion to the inclined optic axes and the Greek χλωρο "chloros," for "green," its typical color. Clinochlore was originally named chlorite in 1789 by Abraham Gottlob Werner from the Greek χλωρο "chloros," for "green," its typical color. There are many named synonyms or varieties of clinochlore. Many names that have been attributed to minerals now called clinochlore, as well as chamosite, include: baltimorite, berlauite, chlorite, chlorophaeite, chromchlorit, corundophilite, daphnite, delessite, diabantite, euralite, faecherstein, grengesite, grochauite, helminthe, kaemmererite, kotschubeite, leuchtenbergite, lophoite, ogkoite, pattersonite, pennine, penninite, prochlorite, pyknochlorite, rhodochrome, rhodophyllite, ripidolite, rumpfite, seraphinite, sheridanite, specksten, talgsten, and many others.
One of the most common members of the chlorite group. It forms a solid solution series with its slightly less common Fe2+-analogue chamosite. Because iron-bearing clinochlore may be oxidized, its appearance and optical properties may vary widely. Minor chromium substitution for Al may make clinochlore look pink to pale purple. Alteration of chlorites may proceed to vermiculite-like or mixed layered structures. Stacking disorder is common.

Sheridanite is an Al-rich variety.
Sudoite is a chemically similar, Al-rich member of the chlorite group.
