Macroscopic Description: Tim McCoy, Lisa Collins
These meteorites exhibit a common external appearance. They have a knobby surface with numerous rounded protrusions up to 1 cm across intermixed with indentations containing a macroscopically jointed mineral.

Microscopic Description: Tim McCoy, Linda Welzenbach
These meteorites were examined from a cut surface of LAP 03593, which displays a sub equal mixture of metal and sulfide with trace amounts of schreibersite and silicates or graphite. The troilite occurs as irregular blobs up to 3 cm in length each of which is composed of multiple troilite crystals 3-5 mm across and exhibit prominent parallel jointing. The metal contains swathing kamacite rims typically 1 mm thick and short irregular bars of kamacite approximately < 0.5 mm. A heat altered α2 structure extends up to 5 mm from the exterior weathered surface, and a highly altered fusion crust may be preserved in some places. The meteorites are similar to the IAB iron Pitts and the ungrouped iron Soroti, but exhibit coarser kamacite band widths than either, and lack the abundant silicates seen in Pitts.
