Writeup from AMN 17(1):

Sample No.: RKP92401; 92402

Location: Reckling Peak

Dimensions (cm): 2.5 x 1.8 x 1.5; 2.5 x 2.5 x 1.0

Weight (g): 7.0; 8.0

Meteorite Type: C2 chondrite

 

Macroscopic Description: Carol Schwarz

Both of these specimens are very weathered. RKP92401 retains no fusion crust and its exterior has a greenish color, and numerous large fractures. The little remaining fusion crust on 92402 is thick and frothy. The interior of both of these samples is black with numerous small rusty white Inclusions.

 

Thin Section (RPK92401,2; 92402,2) Description: Brian Mason

The sections are so similar that these meteorites are probably paired, and paired with RKP92400. The sections show a few chondrules, up to 1.2 mm across, irregular aggregates, and small mineral grains in a black matrix. The minerals are mostly olivine, with minor pyroxene. Olivine compositions are mostly near Mg2SiO4, with a few iron-rich grains. Pyroxene compositions range from Fs2 to Fs5. The meteorite is a C2 chondrite.
