Biduna Blowhole 003 31°01’10.7"S, 131°18’14.2"E South Australia, Australia Found: 6 Apr 2011 Classification: Ordinary chondrite (L6) History: Single piece found by A. Tomkins on the Nullarbor Plain. Physical characteristics: Small stone with 100% dark brown fusion crust. Petrography: (E. Mare, Monash) Stone shows few recognizable chondrules - it is mostly recrystallized matrix. Chondrule types include POP and RP. Fe-Ni metal grains (3-5%) to 500 μm. Troilite grains (3%) to 300 μm. There is only minor oxidation of metal and troilite, with 1% oxides in this meteorite. Olivine grains show undulose extinction, shock fractures, and mosaicism. Geochemistry: (E. Mare, Monash) Microprobe analyses show that olivine and pyroxene compositions are uniform: olivine Fa24.6-26.5, mean=25.4 mol%, std=0.83, n=4; Low-Ca pyroxene Fs21.4-22.4, mean=21.73 mol%, std=0.43, n=5. Classification: Ordinary chondrite (L6, S4, W1) | ||||||||||||||||||||||||||||||||||||||
