Meteorite Type: Iron with silicate (orthopyroxene?) inclusions

Physical Description: Roberta Score,

The overall color of this meteorite is deep reddish-brown. Many greenish-brown, platey silicate inclusions as large as 1.2 cm are obvious. The dimensions of this sample are ~26 x 18.5 x 13 cm.

Petrographic Description: Arch Reid

The meteorite is an iron with slightly weathered exterior in which are set silicate fragments about 5 mm in average size. The most common fragments of this type are greenish single crystals showing cleavage that are probably orthopyroxenes. These silicate fragments appear to be present throughout the meteorite. To confirm their presence in the interior a ~.5 cm slice was cut from a protruding portion (slice is triangular, approximately 4 x 2.5 cm). The major portion of the slice is kamacite with lesser taenite. Approximately ten percent of the interior consists of ellipsoidal to subangular inclusions which are dominantly troilite, silicate, or troilite plus silicate. The silicate has the composition of a magnesian orthopyroxene in the largest inclusion, a second phase may be intergrown with the pyroxene. Other phases present include chromite and schreibersite. The composition of the pyroxene has not been accurately determined but is estimated to be around Wo2En73Fs25. The meteorite is an iron with abundant silicate inclusions.
