Writeup from MB 104:

Ooldea 005 30°34’13.40"S, 131°46’26.60"E

South Australia, Australia

Purchased: 2013 Apr 09

Classification: Ordinary chondrite (H5)

History: Seven fragments over ~10 m² found by A Langendam

Physical characteristics: Several flatish blocky fragments up to 5 cm, several with partial fusion crust, weathered to brown-red.

Petrography: (A. Tait, Monash) Poorly defined chondrules inside a recrystallized matrix. Plagioclase crystals are small (<50 μm). Chondrule populations include: POP, RP, PO, BO, GOP. Olivine grains contain shock lamellae and shock darkeneing. Weathering of FeNi and troilite is ~80% complete. Large corrosion cavities exist inside weathered metal grains. These are often connected by extensive iddingsite veins.

Geochemistry: (A. Tait, Monash) FEG-SEM analyses show that olivine and pyroxene are uniform in their composition: olivine Fa_19.0-19.5, mean Fa_19.3±0.2, n=5; Low-Ca pyroxene Fs_16.7-17.2, mean Fs_16.9±0.3, n=6.

Classification: Ordinary Chondrite (H5, S3, W3)

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