Sample No.: RKPA80232

Location: Reckling Peak

Field No.: 1293

Weight (gms): 80.1

Meteorite Type: H4 Chondrite

 

Physical Description: Roberta Score

Brownish-black fusion crust covers most of the specimen. Chipping exposed a discontinuous weathering rind, 1-3 mm thick. The unweathered interior material is medium to dark gray in color, with many light and dark colored irregular and rounded inclusions. Oxidation halos are uniformly scattered throughout the interior. Dimensions: 4.5 x 3.0 x 2.5 cm

 

Petrographic Descriptions: Brian Mason

The section is made up largely of an aggregate of chondrules, ranging up to 1.2 mm across. They are set in a granular groundmass of olivine and pyroxene, with minor amounts of nickel-iron and troilite. Some of the pyroxene is polysynthetically twinned clinobronzite. Brown limonitic staining is extensive, concentrated around the metal grains. Fusion crust is present along one edge. Microprobe analyses gave the following compositions: olivine Fa18; pyroxene, Fs16. The meteorite is classified as an H4 chondrite.
