Writeup from MB 100:

Ooldea 001        30°32’45.7"S, 131°58’13.8"E

South Australia, Australia

Found: 12 Apr 2010

Classification: Ordinary chondrite (L6)

History: Several broken weathered pieces were found on the surface by A Tomkins, and then another 30 odd pieces were recovered by the team over an area of ~ 100 m2.

Physical characteristics: Many fragments of weathered dark brown material, no fusion crust discernible.

Petrography: (A. Tomkins, Monash) Poorly defined chondrules to 6 mm, sit in a strongly recrystallized matrix. Some plagioclase-dominated domains exceed 300 μm. Chondrule types include RP, POP, PP, BO and PO. Olivine grains show mosaicism and planar deformation fractures, plagioclase has been converted to maskelynite. Fe-Ni metal grains are almost completely rusted out, and the majority of troilite has been destroyed by weathering.

Geochemistry: (A. Tomkins, Monash) Microprobe analyses show that olivine and pyroxene have uniform compositions: olivine Fa25.0-26.1, mean=25.44 mol%, std=0.41, n=5; Low-Ca pyroxene Fs21.7-22.2, mean=21.90 mol%, std=0.21, n=5.

Classification: Ordinary chondrite (L6, S5, W3)
