Writeup from AMN 5(1):

Sample No.: RKPA80203

Location: Reckling Peak

Field No.: 1093

Weight (gms): 3.8

Meteorite Type: H6 Chondrite


Physical Description: Roberta Score

Thin fusion crust remains on this small specimen. There is nothing unweathered remaining on this stone. Dimensions: 2 x 1.5 x 0.5 cm


Petrographic Description: Brian Mason

Chondritic structure is barely perceptible, the sparse chondrules tending to merge into the granular aggregate of olivine and pyroxene, with minor plagioclase, nickel-iron, and troilite. Weathering is extensive, with numerous thin limonite veinlets throughout the section. The meteorite appears to have been considerably fractured and the minerals partly granulated. Microprobe analyses give the following compositions: olivine, Fa19; orthopyroxene, Fs17; plagioclase, An12. The meteorite is classified as an H6 chondrite. Stone is paired with RKPA80206, 80208, 80211, 80213, 80214, 80221, 80231, 80254, 80255, 80262, 80265, and 80266.
