Species: | Augite var: Fassaite |
Formula: | (Ca,Na)(Mg,Fe2+,Al,Fe3+,Ti)[(Si,Al)2O6] |
Comments: | While Ca-Al-Ti rich Clinopyroxene in Angrites is quite properly defined as Augite. The prominence of Ti-rich Augite in Angrites makes the terms 'Fassaite' and 'Fassaitic Pyroxene" virtual synonyms in the meteoritical literature. |
