Writeup from MB 100:
O’Malley 014 30°53’06.6"S, 131°22’48.4"E South Australia, Australia Found: 9 Apr 2011 Classification: Ordinary chondrite (H6) History: Two pieces found by E. Mare on the Nullarbor Plain. Physical characteristics: Two small flatish pieces. Petrography: (E. Mare, Monash) Few recognizable chondrules (to 2 mm) in a recrystallized and rusted matrix. Plagioclase to 100 μm. Chondrule types include CC, PP, PO, RP and POP. Fe-Ni metal grains (<1%) <100 μm. Troilite grains (5%) are larger (up to 300 microns, average 50-100 microns). Oxides have heavily replaced metal and troilite and make up ~20% of the meteorite. Olivine grains have weak undulose extinction. Geochemistry: (E. Mare, Monash) Microprobe analyses show that olivine and pyroxene compositions are uniform: olivine Fa19.6-20.1, mean=19.57 mol%, std=0.38, n=6; Low-Ca pyroxene Fs17.1-17.9, mean=17.59 mol%, std=0.28, n=9. Classification: Ordinary chondrite (H6, S2, W3) | ||||||||||||||||||||||||||||||||||||||
