Ooldea 021 30°38’31.0"S, 131°54’58.5"E South Australia, Australia Find: 26 Apr 2017 Classification: Ordinary chondrite (LL3) History: A single black specimen found amongst other black terrestrial rocks and limestone gibber by A. Tait Physical characteristics: Black weakly magnetic sample, ~60% fusion crust. Petrography: (D. Steele) Chondrules are sharply defined in an opaque matrix. Large chondrules between 1 and 1.5 mm are common. Chondrule types include BO, RP, GOP, GP, PO, POP, PP, cryptocyrstalline and poikilitic. Mineralogy consists of olivine, pyroxene, minor Fe-Ni metal and troilite. Olivine displays straight extinction. Fe-Ni metal and troilite is 30%-60% oxidised. Geochemistry: (D. Steele) Microprobe analysis shows olivine and pyroxene composition is widely variable: olivine Fa17.1-49.5, mean = Fa28.3, std = 12.83, n = 5; orthopyroxene Fs8.35-38.1, mean = Fa22.6, std = 11.86, n = 5. Classification: Ordinary Chondrite (LL3, S1, W2) | ||||||||||||||||||||||||||||||||||||
