Writeup from MB 108:
Ooldea 011 30°30’9.30"S, 131°51’23.50"E South Australia, Australia Find: 2015 Apr 15 Classification: Ordinary chondrite (LL6) History: One fragment found by A. Tait, embedded in a cryptogamic soil horizon. Found during the Monash University meteorite recovery expedition. Physical characteristics: One oval fragment 18 mm long, no fusion crust. Contains crosscutting calcite/gypsum weathering veins. Petrography: (A. Tait, Monash) Chondrule edges are poorly defined, marked by extensive recrystallization of the matrix. BO and POP relict chondrules are rare, with equilibrated edges. Large (>100 μm) skeletal plagioclase grains exist across most the sample, with blebs of FeNi-alloy melt. Fe-oxide weathering is extensive with <5 wt% FeNi and/or sulfides remaining. Olivine show undulose extinction, but there are no indicators of higher shock. Geochemistry: (A. Tait, Monash) EDS analyses show that olivine and pyroxene compositions are uniform: olivine Fa25.7-28.5, mean= Fa26.9±1.0 (N=11). Low-Ca pyroxene Fs20.4-23.8Wo1.8-1.2, mean Fs21.3±1.0Wo1.5±0.2 (N=13). Classification: Ordinary Chondrite (LL6, S2, W4) Specimens: The main mass and a thin section are held at Monash Under the curation of A. Tomkins. | ||||||||||||||||||||||||||||||||||||||||
