Writeup from AMN 4(2):

Sample No.: RKPA80233

Location: Reckling Peak

Field No.: 1096

Weight (gms): 413.5

Meteorite Type: H5 Chondrite


Physical Description: Roberta Score,

Patches of fusion crust cover all but one planar, fracture surface. This surface contains numerous chondrules which can easily be plucked out. A small area of unweathered interior material contains dark inclusions. Dimensions: 8.5 x 6.5 x 5 cm.


Petrographic Description: Brian Mason

Chondritic structure is moderately well developed, with chondrules ranging up to 2.4 mm in diameter. The chondrules are set in a granular ground-mass which consists largely of olivine and pyroxene with minor amounts of nickel-iron, troilite, and plagioclase. There is a considerable amount of limonitic staining throughout the section, concentrated around the metal grains. Microprobe analyses gave the following mineral compositions: olivine, Fa18; orthopyroxene, Fs16; plagioclase, An11. The meteorite is classified as an H5 chondrite.
