Premier Downs 002        30°41.3’S, 125°30.8’E

Western Australia, Australia

Found: 2008

Classification: Ordinary chondrite (LL5-6)

History: A broken and weathered stone found ~20 km north of the Kinclaven Homestead.

Physical characteristics: (A. W. R. Bevan, WAM) The broken fragment, weighing 124.6 g, is iron stained and irregular in shape (7 × 5 × 4 cm). Some fresh fusion crust remains on one face. On broken surfaces the brecciated interior is clearly distinguished by light-colored, crystalline clasts to 1.5 cm set in dark chondritic matrix.

Petrography: (A. W. R. Bevan, WAM) Brecciated chondrite with highly crystalline clasts to 1.5 cm, without discernable chondrules set in a dark matrix containing recognizable chondrules, chondritic fagments of lower petrologic type and shock veins. Chondrules are variably discernible in the matrix and chondritic clasts. Metal and troilite grains are locally shock melted. Metal includes kamacite, taenite and tetrataenite. Accessory minerals include troilite and chromite.

Geochemistry: (A. W. R. Bevan and P. J. Downes, WAM) Crystalline clast olivine Fa32.1; low-Ca pyroxene Fs25.8Wo2.1; in chondrules and matrix, olivine Fa28.5; low-Ca pyroxene Fs24.8 Wo 1.1; kamacite Ni=5.9 Co=2.0 (all wt.%); chromite Cr# 86.1 Fe# 92.6.

Classification: Ordinary chondrite (LL5-6); S4; W2

Specimens: Type specimen and two thin sections WAM
