Keyword Definition

High Chrome Diopside

Diopside is a member of the clinopyroxene group, with the general formula XY(Si,Al)2O6 (where X represents Ca, Na, Fe2+, Mg and more rarely Zn, Mn and Li and Y represents ions of smaller size, such as Cr, Al, Fe3+, Mg, Mn, Sc, Ti, V and even Fe2+).  The composition of pure diopside is CaMgSi2O6.  High Cr diopside is defined here as containing more than 1.4 wt% Cr2O3.
