Macroscopic Description - Mitchell Haller | |
40% of the exterior has black fusion crust with minor fractures. Areas without fusion crust are gray colored with yellow and white inclusions and chondrules. The interior is a dark gray matrix with yellow and white inclusions/chondrules. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section exhibits large chondrules (up to 2 mm), CAIs and AOAs in a dark matrix. Olivines range from Fa1-14, with most Fa1-2, and pyroxenes of Fs1. The meteorite is an unequilibrated carbonaceous chondrite, probably a CV3. | |
Reclassification Notes (AMN 46,1) | |
Reclassification and pairing based on Raman spectroscopy (petrologic type 3.7), and on Ni content of metal and sulfide and magnetic susceptibility (Oxidized A). Details are reported in Righter et al. (2022); doi: 10.1111/maps.13932. |
