Macroscopic Description - Cecilia Satterwhite, Robbie Marlow and Carol Schwarz
At least 50% of each of these nine specimens are covered with weathered fusion crust. The fusion crust on EET92042 is frothy and black, where it is dull and brown on the other eight specimens. Fractures penetrate the interior of all specimens and they are all moderately to heavily oxidized. A1 of the interiors are rusty brown to black in color and contain numerous chondrulistic inclusions that range from 1 mm to 4 m m in size. Small amounts of white evaporite deposit were noted on 92062 and 92092. The evaporite deposit on 92042 has a bluish color.
Thin Section Description (,7) - Brian Mason
The sections are so similar that the meteorites can confidently be paired, and paired with the EET87711 group (Antarctic Meteorite Newsletter 12(3), 1989). They show a close-packed aggregate of chondrules and chondrule fragments, up to 2.8 mm across, in an opaque matrix which contains 10-20% nickel-iron as small globules and rimming chondrules. Fine-grained disseminated troilite may be present in small amounts. Weathering is extensive, with limonitic staining throughout the sections. Most chondrules consist of granular olivine or olivine-pyroxene; some have intergranular pale brown glass. Most of the mineral grains are close to Mg2SiO4 and MgSiO3 in composition: olivine, Fa1-6 (Fa1-32 in 92042,4); pyroxene, Fs2-10. The meteorite is a C2 chondrite of the Renazzo subgroup.
