Keyword Definition

Chondrodite

Chondrodite is the most common member of the humite group of minerals, which have the general formula An(SiO4)m(F,OH)2.  Chondrodite has an ideal end member formula of Mg5(SiO4)2F2.

In the humite series Mg2+ is replaced by Fe2+, Mn2+, Ca2+ and Zn2+ in that order of abundance, though Mg2+ always predominates.

Chondrodite is found largely in metamorphic contact zones between carbonate rocks and acidic or alkaline intrusions where fluorine has been introduced by metasomatic processes.
