Sleeper Camp 026        30°10’25"S, 126°26’04"E

Western Australia, Australia

Found: 2005

Classification: Ordinary chondrite (L6)

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

Physical characteristics: (A. W. R. Bevan, WAM): Rounded, slightly conical stone, with a maximum dimension of 5 cm is covered by fusion crust.

Petrography: (A. W. R. Bevan, WAM): Microscopically, the meteorite contains barely discernible chondrules set in a recrystallized, iron-stained matrix. Large grains (>50 µm) of plagioclase are partially converted to maskelynite. Olivine shows mosaicism, and closely spaced planar fractures and deformation features. Metal includes kamacite and taenite. Accessory minerals include troilite and chromite.

Geochemistry: (A. W. R. Bevan and P. J. Downes, WAM) Mineral compositions as determined by EMP: olivine Fa25.7; low-Ca pyroxene Fs21.9Wo1.5; kamacite Ni=6.21 Co=0.96 (all wt%); chromite Cr# 86.9.

Classification: Ordinary chondrite (L/LL6); S4/5; W2.

Specimens: Main mass and one thin section at WAM.
