Pyroxene quadrilateral

Pyroxene quadrilateral
Pyroxene quadrilateral This pyroxene quadrilateral is showing example compositions, where enstatite is pure magnesium pyroxene (Mg2Si2O6) and ferrosilite is pure iron pyroxene (Fe2Si2O6). Diopside is a pyroxene with 50% calcium and 50% magnesium in the structure (CaMgSi2O6); hedenbergite is a pyroxene with 50% calcium and 50% iron in the structure (CaFeSi2O6). I am working on this graphic for Lane et al. (2018), a paper in which the blue squares represent pyroxene mineral samples that will be discussed in the paper, and orange dots represent pyroxene compositions studied but will not be discussed specifically in the paper.
