Macroscopic Description - Cecilia Satterwhite
Half of the exterior is covered with black/brown fusion crust and heavy oxidation. Some areas are rusty and evaporites are present. The interior is a dark gray to black matrix with metal and some oxidation. This meteorite was very difficult to break.
Thin Section Description (,4) - Cari Corrigan and Tim McCoy
This meteorite consists largely of prismatic or granular enstatite (grain size 0.1-0.2 mm) and nickel-iron, and minor amounts of sulfide and plagioclase. Only vague traces of chondritic structure are visible in this section. One end of the section exhibits a metal grain (8 x 3 mm) that is dominantly composed of iron nickel metal with rounded troilite-daubreelite inclusions up to 700 microns across, and lathes of graphite up to 1 mm in length. A single grain of sinoite was also observed in the section. Microprobe analyses show that the enstatite is almost pure MgSiO3 (Fs0.1-0.4). The meteorite is an EL6 chondrite.
