Macroscopic Description - Cari Corrigan and Tim McCoy
The main mass of this meteorite is slightly flattened. The surface shows numerous pits and indentations, some of which have exposed silicates within them. The entire surface is brown and rust haloes are frequent.
Thin Section Description (,2) - Cari Corrigan and Tim McCoy
This section is a subequal mixture of metal and silicates. Silicates are dominantly pyroxene (Fs26Wo2) and feldspar (An90Or0.5) with rare olivine (Fa24), phosphates and silica. The metal consists of kamacite with lesser taenite (exhibiting rims of tetrataenite) and polycrystalline troilite. Fusion crust is present on one edge of the section and α2 structure reaches approximately 2 mm into the sample from that edge. The meteorite is a mesosiderite.
