Writeup from MB 101:

Camel Donga 053        30°19’S, 126°37’E

Western Australia, Australia

Found: 2008

Classification: Ordinary chondrite (LL5-6)

History: A single stone was found lying on the surface within the strewnfield of the Camel Donga eucrite in the Nullarbor Region.

Physical characteristics: The rounded, orientated and almost completely crusted stone has only minor surface weathering.

Petrography: (A. W. R. Bevan, WAM) The stone is a brecciated chondrite composed of highly crystalline clasts (up to 1.5 cm) with granular textures, mixed with less recrystallized clasts set in a shocked and comminuted matrix. Olivine shows mosaicism and planar features. The crystalline clasts contain large (>50µm) grains of plagioclase, some converted to maskelynite. Extensive shock veining often along clast boundaries. Metal includes kamacite, taenite and tetrataenite. Accessory minerals include troilite, chromite and chrome spinel.

Geochemistry: (A. W. R. Bevan and P. J. Downes, WAM) In crystalline clasts olivine mean Fa31.6 (n=24); pyroxene Fs25.7Wo 3.3, olivine mean Fa26.5 (n=5) in one less crystalline clast; low-Ca pyroxene Fs25.6Wo1.9; plagioclase An11.2Ab82.2Or6.6; kamacite Ni=6.7 Co=2.6 (all wt%); chromite Cr#86.9 #Fe90.5; and chromian spinel containing up to 8wt% Cr.

Classification: Ordinary chondrite (LL5-6); S4; W2. Camel Donga 053 is a breccia of LL5 and LL6 clasts in a comminuted matrix of the same, with some shock veins.

Specimens: Type specimen and two thin sections WAM
