Writeup from MB 100:
O’Malley 006 30°39’25.2"S, 131°28’41.3"E South Australia, Australia Found: 07 Apr 2011 Classification: Ordinary chondrite (H5) History: Single piece found by E. Mare on the Nullarbor Plain. Physical characteristics: Small flattish stone, dark reddish brown, some lichens. Petrography: (E. Mare, Monash) Stone shows moderately well defined chondrules in a recrystallized, rusted matrix. Chondrule types include RP, POP, CC, PO, PP. Fe-Ni metal grains (<<1%) average ~5 μm. Troilite grains (3%) are up to 200 microns and show some oxidation. Metal and troilite are partly replaced by oxides which make up ~7% of the meteorite. Olivine grains show sharp extinction, however there are extensive melt networks where brecciated silicates are suspended in oxides after troilite and metal. Geochemistry: (E. Mare, Monash) Microprobe analyses show that olivine and pyroxene compositions are uniform: olivine Fa18.7-19.1, mean=18.84 mol%, std=0.19, n=4; Low-Ca pyroxene Fs16.5-17.0, mean=16.83 mol%, std=0.24, n=4. Classification: Ordinary chondrite (H5, S3, W3) | ||||||||||||||||||||||||||||||||||||||
