Macroscopic Description - Kathleen McBride | |
25% of the exteriors have brown fusion crust exhibiting polygonal fractures. The interiors are a charcoal gray matrix with white, light gray and rust colored chondrules, 1-3 mm in diameter. The meteorites are moderately hard. | |
Thin Section Description (,2) - Gretchen Benedix, Linda Welzenbach, Tim McCoy | |
The sections exhibit large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa0-28 and pyroxenes from Fs0-3. The meteorites are CV3 chondrites. | |
Reclassification Notes (AMN 46,1) | |
Reclassification and pairing based on Raman spectroscopy (petrologic type 3.6), and on Ni content of metal and sulfide and magnetic susceptibility (Oxidized B). Details are reported in Righter et al. (2022); doi: 10.1111/maps.13932. |
