Writeup from MB 100:
Pingrup 33°34’59.38"S, 118°39’23.83"E Western Australia, Australia Found: 2011 Classification: Ordinary chondrite (H5, melt breccia) History: A mass of unknown original weight was found on a rock dump on agricultural land near the township of Pingrup. The meteorite was broken by the finder and a sample sent for assay. Subsequently, the stone was brought to the WAM. Physical characteristics: The irregular, broken mass is deeply weathered and mantled in a crust of brown oxides and oxyhydroxides of iron. The interior is dark and heavily stained with iron oxides. Petrography: (A. W. R. Bevan, WAM) Microscopically there are few discernible chondrules. The stone is extensively shock-melted and abundant, large, blackened shock melt veins pervade the fabric of the meteorite. Vestiges of the original chondritic texture are also severely shocked. Most of the metal and troilite grains have been shock-melted and now occur as large Fe/FeS globules with a eutectic texture, some metal and troilite remain unmelted. Accessory minerals include chromite. Geochemistry: (A. W. R. Bevan and P. Downes, WAM) Olivine Fa19.1; orthopyroxene Fs16.8Wo1.5; metal Ni=8.4 Co=0.46 (all wt %); chromite Cr# 83.8, Fe# 82.7. Classification: Ordinary chondrite (H5-melt breccia); S5; W3. Specimens: Main mass and one thin section at WAM. | ||||||||||||||||||||||||||||||||||||
