It is often associated with such minerals as epidote and actinolite. It is a major component of slates, phyllites, greenstone and greenschists. Some varieties form during the primary crystallization of hydrous magmas. Chlorite may also form in soils and persist as a detrital mineral in sedimentary rocks. It is an abundant mineral in Wisconsin.
