Physical Description: Roberta Score

No fusion crust remains on this weathered meteorite. Many single crystals of pyroxene are scattered on the surface. The largest is 3 x 3 mm in dimension and fell out during chipping. The interior is highly weathered. Sample is paired with RKPA80246, RKPA80258, and RKPA80263. Dimensions: 3 x 2 x 1.5 cm


Petrographic Description: Brian Mason

The section shows clasts of orthopyroxene, up to 2 mm across, in a nickel-iron matrix (the matrix extensively altered to limonite). Microprobe analyses show the pyroxene has essentially uniform composition, Wo2En74Fs24. This specimen is a weathered fragment of RKPA79015.
