Writeup from MB 89:
Grove Mountains 020025 Antarctica Found 2002 Carbonaceous chondrite (CM2) A fragment weighs 3.55 g, and retains a part of fusion crust. Classification and Mineralogy (CAS): Chondrules are small (<500 μm, most 100-300 μm in diameter), and less abundant (26 vol%) than the opaque matrix (~ 70 vol%). Other components are many mineral fragments, less abundant Ca-Al-rich inclusions and amoeboid olivine aggregates, and rare metallic Fe-Ni and sulfides. Phyllosilicates are very common. All Ca-Al-rich inclusions are strongly altered. Olivine (Fa10.2±16) and low-Ca pyroxene (Fs1.8±1.1) are highly heterogeneous. Shock stage, S1; weathering grade, W1. | ||||||||||||
