Hedenbergite

Pyroxenes

Hedenbergite, Ca 6, is the iron group having a monoclinic crystal system. The mineral is extremely rarely found as a pure substance, and usually has to be synthesized in a lab. It was named in 1819 after M.A. Ludwig Hedenberg , who was the first to define hedenbergite as a mineral. Contact metamorphic rocks are the primary geologic setting for hedenbergite. This mineral is unique because it can be found in chondrites (calc–silicate metamorphic rocks ). Since it is a member of the pyroxene family, there is a great deal of interest in its importance to general geologic processes.
