A stony meteorite containing abundant small spheroidal to ellipsoidal bodies known as "chondrules". It belongs to the low-iron ("L") chemical group and to petrologic type "6" indicating substantial textural modifications (such as in the definition of the chondrule margins) during high-temperature annealing. The essential minerals present are orthopyroxene, olivine, troilite, kamacite and taenite with minor amounts of plagioclase feldspar (or maskelynite), clinopyroxene, chromite, ilmenite, chlorapatite and/or merrillite, and probably tetrataenite.
-60+100 US sieve mesh fraction with some of Fe-Ni removed (presumably magnetically). This is part of a 3.352 kg sample that was used for obtaining mineral separates.
