Macroscopic Description - Kellye Pando | |
Possible fusion crust covers about 40% of the exterior. It is dark brown with orange rust and shiny varnish all over.

Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section consists of an equigranular aggregate of olivine, pyroxene, plagioclase, and metal with minor sulfide and chromite. Average grain size is 0.3 mm with some grains up to 1 mm. The section is modestly weathered. Olivine (Fa7) and pyroxene (Fs8) are homogenous. Three calcic pyroxene grains were analyzed (Fs3). The meteorite is an acapulcoite. |
