Writeup from AMN 5(1):

Sample No.: RKPA80219

Location: Reckling Peak

Field No.: 1305

Weight (gms): 21.5

Meteorite Type: L6 Chondrite


Physical Description: Roberta Score

This stone is totally covered with black fusion crust. A discontinuous weathering rind was exposed during chipping along with a light gray interior with lighter and darker colored inclusions. Dimensions: 3 x 2 x 1.5 cm


Petrographic Description: Brian Mason

Chondritic structure is barely perceptible, the sparse chondrules merging with the granular matrix, which consists of olivine and pyroxene, with minor amounts of plagioclase, nickel-iron, and troilite. Remnants of fusion crust rim part of the section. A minor amount of limonitic staining is present around metal grains. Microprobe analyses give the following compositions: olivine, Fa25; orthopyroxene, Fs21; plagioclase, An11; one grain of diopside was noted. The meteorite is an L6 chondrite.
