Writeup from AMN 5(1):

Sample No.: RKPA80234

Location: Reckling Peak

Field No.: 1119

Weight (gms): 136.2

Meteorite Type: LL5 Chondrite

 

Physical Description: Roberta Score

fusion crust covers only one flat surface. While the other surfaces have weathered to a reddish-brown color, several rounded and irregular yellow colored inclusions are obvious on the exterior. Chipping revealed a moderately (heavy in some areas) weathered interior. The matrix material is medium to dark gray and contains numerous chondrules. Dimensions: 6 x 5 x 2 cm

 

Petrographic Description: Brian Mason

Chondritic structure is barely discernable, the sparse chondrules being largely obscured by extensive brecciation throughout the section. The section shows an aggregate of granular olivine and pyroxene, with a little troilite and nickel-iron. Brown limonitic staining pervades the section. Microprobe analyses gave the following compositions: olivine, Fa26; pyroxene, Fs22. The meteorite is classified as an LL5 chondrite.
