Writeup from AMN 5(1):

Sample No.: RKPA80217

Location: Reckling Peak

Field No.: 1397

Weight (gms): 7.5

Meteorite Type: H5 Chondrite

 

Physical Description: Roberta Score

Black fusion crust covers one surface of this flat specimen. The remaining surfaces are highly weathered. Chondrules are visible. The interior is totally weathered. This sample resembles RKPA80218. Dimensions: 2 x 2 x 1 cm

 

Petrographic Description: Brian Mason

Chondritic structure is well developed, with chondrules 0.3-1.0 mm in diameter. They are set in a granular matrix of olivine and pyroxene, with minor amounts of nickel-iron, troilite, and a little plagioclase. Remnants of fusion crust are present on one edge of the section. Brown limonitic staining is pervasive throughout the section. Microprobe analyses give the following compositions: olivine, Fa18; pyroxene, Fs15; plagioclase, An12. The meteorite is classified as an H5 chondrite.
