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) | ||||||||||||||||||||||||||||||||||||||
