Writeup

Writeup from AMN 5(1):

Sample No.: RKPA80228

Location: Reckling Peak

Field No.: 1307

Weight (gms): 11.1

Meteorite Type: L5 Chondrite

Physical Description: Roberta Score

This meteorite is covered with a weathered fusion crust. Several fractures penetrate the interior of the stone. Weathering has disguised all of the interior features of the specimen. Dimensions: 2 x 2 x 1.5 cm

Petrographic Description: Brian Mason

Chondrules are prominent, ranging from 0.3 to 2.4 mm in diameter. They are set in a granular matrix of olivine and pyroxene, with minor subequal amounts of nickel-iron and troilite. Brown limonitic staining pervades the section. Microprobe analyses give the following compositions: olivine, Fa23; pyroxene, Fs19. The meteorite is classified as an L5 chondrite.
