Macroscopic Description - Kellye Pando

Rough black fusion crust with fractures and rust spots covers about 40% of the exterior. Exposed area is grey matrix that is heavily weathered with a dark red-brown varnish covering most of it. Fresh interior is grey matrix with orange rust and metal inclusions throughout.

Thin Section Description -

The section consists of a fine to medium equigranular mixture of olivine (Fa₇) and pyroxene (Fs₇Wo₁) with plagioclase that poikilitically encloses mafic silicates. No chondrules or relic chondrules were observed. Veins of, and areas enriched in metal and/or sulfide occur commonly. This meteorite is an ungrouped primitive achondrite, possibly either in the acapulcoite/lodranite or part of the winonaite/IAB group.
