Writeup from MB 108:
Antarctica 006 Antarctica Find: 1992-1993 Classification: Ordinary chondrite (L5) History: A single specimen weighing 84 g was collected by a Canadian pilot supporting ANSMET searching during the 1992-93 season, from an unspecified location within Antarctica. Physical characteristics: The single, irregular mass is ~70% covered in fusion crust. Iron staining is prevalent. Interior surfaces show evidence for brecciation. Petrography: (C. Herd, UAb) Optical and microprobe examination of a polished thin section shows a highly brecciated texture with a few readily-delineated chondrules in a cataclastic matrix. Shock effects include weak mosaicism and PFs in olivine. Minor iron staining is present locally. Weathering grade according to Zurfluh et al. (2016); shock stage according to Fritz et al. (2017). Geochemistry: (C. Herd, UAb) Data obtained by EMP examination of carbon-coated thin section: Olivine Fa24.4±0.3 (n=53); Low-Ca Pyroxene Fs20.7±0.3Wo1.3±0.6 (n=45). Classification: Ordinary chondrite, L5 Specimens: Entire specimen, including one thin section is at UAb. Difference between recovered weight and type specimen is due to cutting losses. | ||||||||||||||||||||||||||||
