Macroscopic Description - Kathleen McBride | |
The exterior of this carbonaceous chondrite has brown/black shiny fusion crust covering 100% of its surface area. It is fractured and has oxidation halos. The interior has a dark matrix with some rust and metal. Irregularly shaped chondrules are light colored, stained with rust. Other inclusions appear rusty, tan and gray in color. | |
Thin Section Description (,2) - Tim McCoy | |
The section exhibits large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa1-31, with most Fa1-5, and pyroxenes from Fs1-2. The meteorite is an unequilibrated carbonaceous chondrite, probably a CV3. | |
Reclassification Notes (AMN 46,1) | |
Reclassification and pairing based on Raman spectroscopy (petrologic type 3.6), and on Ni content of metal and sulfide and magnetic susceptibility (Reduced). Details are reported in Righter et al. (2022); doi: 10.1111/maps.13932. |
