Macroscopic Description -

These highly irregular masses exhibit numerous angular indentations and jagged protrusions. EET 16046 shows one relatively flat surface which appears to sample the original exterior of the parent meteorite.

Thin Section Description (,,1) - Cari Corrigan, Tim McCoy

The sections are composed largely of iron-nickel metal with interspersed silicate grains of up to 0.5 mm. The metallic host is composed of kamacite with large amounts of plessite, which includes clear taenite borders. The silicates include olivine (Fa_3-4), pyroxene (Fs_5-7Wo_1-2) and feldspar. These silicates are intergrown with abundant troilite, graphite and large schreibersite grains. The meteorite is an iron with silicate inclusions and is probably a silicate-bearing, low-Ni IAB iron similar in composition to, e.g., Landes. Pairing with EET 87504/EET 87505/EET 87506 is possible.
