Writeup from AMN 4(1):

Sample No.: RKPA79014

Location: Reckling Peak

Field No.: 1203

Weight (gms): 77.7

Meteorite Type: H5 Chondrite

 

Physical Description: Roberta Score

Sample is totally covered with a black fusion crust. Several cracks penetrate the sample. The interior is mainly weathered with only a small area being un-weathered and light gray in color. Dimensions: 4 x 3 x 3.5 cm.

 

Petrographic Description: Brian Mason

Chondritic structure is well developed, with chondrules ranging from 0.3-1.2 mm across. The chondrules are set in a granular matrix, which consists largely of olivine and pyroxene, with minor amounts of nickel-iron and troilite. Fusion crust, up to 0.5 mm thick, rims part of the section. Considerable weathering is indicated by red-brown limonite filling voids in the fusion crust and by limonitic staining around nickel-iron grains. Microprobe analyses give the following compositions: olivine, Fa18; pyroxene, Fs16. The meteorite is classified as an H5 chondrite.
