Writeup from MB 108:
Ooldea 012 30°34’16.4"S, 131°46’18.1"E South Australia, Australia Find: 9 Apr 2013 Classification: Ordinary chondrite (L5) History: Twelve fragments spread over ~20 m2 found by A Tomkins Physical characteristics: Several flatish blocky fragments up to 4 cm, several with partial fusion crust, weathered to brown-red. Petrography: (J. Savage, Monash) Porphyritic chondrules >1 mm are recognisable amongst well recrystallized matrix. Two porphyritic chondrules <1 mm have troilite rims. Chondrule mesostasis is completely recrystallized. Minerals present are olivine, pyroxene, plagioclase, Fe-Ni metal and troilite. Chondrule types include PO, C, BO, POP, PP, and RP. The majority of olivine, pyroxene and plagioclase grains exhibit undulose extinction. 85% of Fe-Ni metal is weathered, 50-60% of Sulfides. Geochemistry: (J. Savage, Monash) Microprobe analyses show that olivine and pyroxene compositions are uniform: olivine Fa23.0-26.4, mean=Fa24.2, std=1.6, n=5; Low-Ca pyroxene Fs20.3-23.1, mean=Fa21.4, std=1.09, n=5. Classification: Ordinary chondrite (L5, S2, W3) | ||||||||||||||||||||||||||||||||||||
