Writeup from MB 104:

Ooldea 003        30°33’50.88"S, 131°48’14.16"E

South Australia, Australia

Purchased: 2013 Apr 06

Classification: Ordinary chondrite (H4)

History: Single broken specimen found by E Mare

Physical characteristics: Angular 3 cm block with 95% brown-orange fusion crust

Petrography: (A. Tait, Monash) Chondrules have clear edges. Mesostasis shows evidence of initial recrystallization inside POP chondrules. Chondrules range in size form 1 - 2 mm, they include: POP, BO, RP, AP, CC, GOP and RP with clinoenstatite. Olivine shows a weak undulous extinction. Oxidation is almost complete (>95%), with extensive weathering veins and corrosion cavities.

Geochemistry: (A. Tait, Monash) FEG-SEM analyses show that olivine and pyroxene is uniform in their composition: olivine Fa18.4-19.1, mean  Fa18.8±0.2, n=8; Low-Ca pyroxene Fs16.0-16.9, mean  Fs17.0±0.3, n=9.

Classification: Ordinary Chondrite (H4, S2, W3)

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