Macroscopic Description - Kathleen McBride | |
Brown/black fusion crust covers the surface of this meteorite. The interior matrix is gray with low metal and light gray clasts. | |
Thin Section Description (,2) - Tim McCoy, Linda Welzenbach | |
The section exhibits large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa0-3 and pyroxenes from Fs0-3. The meteorite is an unequilibrated carbonaceous chondrite, probably a CV3. | |
Reclassification Notes (AMN 46,1) | |
Reclassification and pairing based on Raman spectroscopy (petrologic type 3.1), 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. |
