Meteorite Type: Mesosiderite


Physical Description: Roberta Score

The heavily weathered exterior surfaces of this meteorite contains several large pyroxene crystals, as large as 5 mm in the longest dimension. Most of the crystals have three cleavage faces showing. Many of these clasts can easily be plucked out. Chipping this thin specimen did not expose any unweathered material. This specimen is paired with RKPA80229, RKPA80258, and RKPA80263. Dimensions: 3 x 1.5 x 1 cm


Petrographic Description: Brian Mason

The section consists largely of-clasts of orthopyroxene, up to 4 mm across, seamed with veinlets of nickel-iron which has been extensively altered to red-brown limonite. Microprobe analyses show the pyroxene has essentially uniform composition, Wo2En74Fs24. The specimen is a weathered fragment of RKPA79015.
