Mineralpedia Details for Chondrodite
Chondrodite
Named for its common occurrence as isolated grains through the Greek word for “grain,” after the Greek word chondrou, meaning “cartilage,” which itself appears microscopically as isolated grains in matrix. Chondrodite is an uncommon mineral that occurs in contact metamorphic zones in limestones and dolostones, and in carbonatites. Some localities for Chondrodite can be found in Finland, Sweden, Italy, France, India, the United States, Canada, South Africa, and a few others.
