Writeup from MB 100:

Sleeper Camp 027        30°09’37"S, 126°20’54"E

Western Australia, Australia

Found: 2005

Classification: Ordinary chondrite (H5)

History: A single stone was found in the Sleeper Camp area of the Nullarbor Region.

Physical characteristics: (A. W. R. Bevan, WAM): The small, weathered, but almost completely crusted stone measures 2.5 × 1.5 × 1.5 cm.

Petrography: (A. W. R. Bevan, WAM): Microscopically, the meteorite contains discernible, but indistinct chondrules set in a moderately crystalline, heavily iron stained matrix. Barred and porphyritic olivine chondrules, and radiating pyroxene chondrules predominate. Incipient, minor shock veins locally disrupt the chondritic texture. Metal includes kamacite, taenite and tetrataenite. Accessory minerals include, troilite and chromite.

Geochemistry: (A. W. R. Bevan and P. J. Downes, WAM): Mineral compositions as determined by EMP: olivine Fa19.8; low-Ca pyroxene Fs17.5Wo1.3; kamacite Ni=6.7 Co=0.5 (all wt%); chromite Cr# 85.5 #Fe83.7.

Classification: Ordinary chondrite (H5); S3; W2.

Specimens: Main mass and one thin section WAM.
