Writeup from MB 109:

Camel Donga 054        30°19’S, 126°37’E

Western Australia, Australia

Find: 2007 Apr 24

Classification: Ordinary chondrite (H6)

History: Found on the surface by K. Hicks on open plain within the strewnfield of the Camel Donga eucrite (A. Bevan, WAM)

Physical characteristics: Physical Characteristics: A crusted, broken, weathered fragment weighing 49.28 g, measuring 5x3x3.5 cm (A. Bevan, WAM).

Petrography: (L. Daly, L. V. Forman, Curtin). Specimen has poorly defined chondrules within a heavily stained red/opaque matrix. The chondrules include types RP, PO, POP, and BO, and chondrule mesostases are crystalline. Sizes range from 0.45-1.8 mm with a mean of 1.1 mm (n=18). Mineralogy consists of olivine, pyroxene, chromite, feldspar, and FeO. Olivine and pyroxene have undulose extinction, and planar fractures. Feldspars are mostly <50 µm but some larger grains were observed. Any metal and sulfide previously present in the sample have been completely replaced with iron oxide > 95 %.

Geochemistry: Mineral Compositions and Geochemistry: EDS, Olivine: Fa20.1±0.6 (n=12). Low Ca pyroxene: Fs17.6±1.2Wo2.3±1.1 (n=6) rare diopside is present Fs6.8Wo46.4. Feldspar Ab86.5± 1.3 with some rare Ca rich varieties Ab60-47.9.

Classification: Ordinary Chondrite, H6, S3, W4

Specimens: The WAM holds the main mass now 47.28 g and one thin section.
