Writeup from AMN 5(1):

Sample No.: RKPA80220

Location: Reckling Peak

Field No.: 1398

Weight (gms): 124.5

Meteorite Type: H5 Chondrite

 

Physical Description: Roberta Score

Thin patchy fusion crust covers the entire meteorite. Several fractures penetrate the interior of the stone. The interior is mostly weathered. Small areas of relatively fresh material are medium gray to yellow gray in color. Dimensions: 5.4 x 4 x 3 cm

 

Petrographic Description: Brian Mason

Chondritic structure is moderately well developed, but is partly obscured by extensive fracturing. The chondrules are set in a matrix of olivine and pyroxene, with minor amounts of nickel-iron and troilite. Brown limonitic staining is present throughout the section. Microprobe analyses give the following compositions: olivine, Fa18; pyroxene, Fs16; accessory merrillite was identified. The meteorite is classified as an H5 chondrite.
