About Angrite meteoriteHide

Angrites, named after the Angra dos Reis, Brazil, fall of 1869, are a relatively rare type of basaltic achondrite with low alkali contents, high Ca/Al ratios, and a distinctive mineral assemblage, generally including Al-Ca-Ti-rich pyroxene, Ca-rich plagioclase, and Ca-rich olivine that may have exsolved the mineral kirschsteinite.

Meteoritical Society Code: Angrite
