Writeup from AMN 16(2):

Sample No.: RKP92400

Location: Reckling Peak

Dimensions (cm): 2.5 x 1.9 x 1.8

Weight (g): 7.8

Meteorite Type: C2 chondrite


Macroscopic Description: Robbie Marlow

Polygonally-fractured fusion crust cover 75% of the exterior of RKP92400. A small amount of evaporite deposit was noted. The interior matrix of this friable carbonaceous chondrite is dark gray with numerous small white inclusions.


Thin Section (,2) Description: Brian Mason

The section shows a few chondrules, up to 0.9 mm across, irregular aggregates, and small mineral grains in a black matrix. The minerals are mainly olivine, with minor pyroxene. Olivine compositions are mostly near Mg2SiO4, with a few more iron-rich grains, up to Fa10. Pyroxene compositions range from Fsl to Fs3. The matrix appears to be mainly iron-rich serpentine. The meteorite is a C2 chondrite.
