Writeup from MB 104:

Ooldea 009 30°36’33.80"S, 131°56’53.50"E

South Australia, Australia

Purchased: 2013 Apr 22

Classification: Ordinary chondrite (H6)

History: Two jigsaw-fitting fragments 30 cm apart found by A. Tait

Physical characteristics: Two fragments jigsaw fit together to make whole fusion crust. Larger fragment has lichen.

Petrography: (S. Nutku, Monash) Chondrules very difficult to discern, indistinct from matrix, sit in an olivine dominated, strongly recrysallized matrix <200 μm. Mineralogy includes olivine, pyroxene, plagioclase, Fe-Ni metal, troilite. Chrondrule types include RP (<1.5 mm), POP (1 mm), BO (1 mm) and GOP. Undulose extinction is observed in 20% of olivine crystals. Weathered troilite has Fe oxide rims. Oxidation approx. 65%.

Geochemistry: (S. Nutku, Monash) Microprobe analyses show olivine and pyroxene compositions are uniform: olivine Fa_19.3-20.2mean Fa_19.8±0.4, n=6; Low-Ca pyroxene Fs_16.8-18.0, mean Fs_17.6±0.4, n=6.

Classification: Ordinary chondrite (H6, S2, W3)

Specimens: All specimens and one thin section held by A. Tomkins.
