Sep 13 2005 Pyroxenes are classified based on the occupancy of the M1 and M2 site In clinopyroxenes larger cations such as Li and Na are in eightfold

Pyroxene Structures

The pyroxene group is composed of minerals of the general formula XYSi2O6 where X and Y are two divalent cations or a monovalent and a trivalent cation
