It occurs in pegmatites in a pyroxenite intrusion as crystals in clinochlore and kassite.

Naldrettite occurs as anhedral grains that are commonly attached to sulfide minerals and are associated with clinochlore.
3.
A massive compact variety of clinochlore used as a decorative carving stone is referred to by the trade name seraphinite.

In most common chlorites, there are 12.0 octahedral cations per O 20 ( OH ) 16 and approximately equivalent amounts of aluminium in tetrahedral and octahedral sites [ e . g . the magnesia chlorite, clinochlore, ( Mg 10 Al 2 ) ( Si 6 Al 2 O 20 ) ( OH ) 16 ] ( Deer et al ., 1992 ).
