Writeup from AMN 5(1):

Sample No.: RKPA80241

Location: Reckling Peak

Field No.: 1074

Weight (gms): 0.6

Meteorite Type: C3V Chondrite

 

Physical Description: Roberta Score

A small amount of fusion crust exists on this tiny specimen. Dimensions: 1.5 x .5 x .5 cm

 

Petrographic Description: Brian Mason

The section shows a close-packed aggregate of chondrules (up to 2.5 mm across) and irregular granular aggregates, set in a small amount of black (probably carbonaceous) matrix. A minor amount of nickel-iron is present, in several forms: as small grains dispersed through some chondrules, concentrated around the margins of some chondrules, and as rare globules up to 0.8 mm across in the matrix. The silicate material consists largely of olivine and polysynthetically twinned clinopyroxene. Well preserved fusion crust, up to 1.2 mm, rims part of the section. Weathering is extensive, with brown limonitic staining pervasive throughout the section. Microprobe analyses show olivine and pyroxene with variable composition; for 30 olivine analyses the Fa range is 0.7-5.5 (except for one of Fa36), and the mean is Fa3; for 15 pyroxene analyses the range is Wo0.3-1.5, En90-98, Fs1-8, with a mean of Wo0.7En95Fs4. The meteorite is tentatively classified as a C3V chondrite.
