Petrogenesis of Erg Chech 002 Achondrite and Implications for an Altered Magma Ocean
This study conducts mineralogical and chemical investigations on the oldest achondrite, Erg Chech 002 (∼4565 million yr old). This meteorite exhibits a disequilibrium igneous texture characterized by high-Mg-number (atomic Mg/(Mg + Fe ^2+ )) orthopyroxene xenocrysts (Mg number = 60–80) embedded in a...
