n. (context mineral English) A nesosilicate mineral with chemical formula (Mg,Fe)₅(F,OH)₂(SiO₄)₂, the most frequently encountered member of the humite group.

Chondrodite is a nesosilicate mineral with formula (Mg,Fe)(SiO)(F,OH,O). Although it is a fairly rare mineral, it is the most frequently encountered member of the humite group of minerals. It is formed in hydrothermal deposits from locally metamorphosed dolomite. It is also found associated with skarn and serpentinite. It was discovered in 1817 on Mt. Somma, part of the Vesuvius complex in Italy, and named from the Greek for "granule", which is a common habit for this mineral.
