Writeup from AMN 4(1):

Sample No.: RKPA79003

Location: Reckling Peak

Field No.: 1185

Weight (gms): 182.2

Meteorite Type: H6 Chondrite

 

Physical Description: Roberta Score

Black fusion crust totally covers all surfaces of this semi-rounded stone. Small areas where the fusion crust has been plucked off reveal a reddish-brown matrix with many inclusions. Numerous attempts to obtain a fresh chip for thin sections failed. Several small exterior chips which may or may not be representative of this stone were obtained. The chips obtained look granular in texture and reddish-brown in color and contain fusion crust. Dimensions: 7 x 4.5 x 3.5 cm.

 

Petrographic Description: Brian Mason

Chondrules are sparse and poorly defined, being barely distinguishable from the granular groundmass, which consists largely of olivine and pyroxene, with minor amounts of nickel-iron, plagioclase, and troilite. Weathering is indicated by moderate limonitic staining around metal grains, and some small areas of brown limonite. Microprobe analyses gave the following compositions: olivine, Fa18; pyroxene, Fs16; plagioclase, An12. The meteorite is classified as an H6 chondrite.
