Macroscopic Description - Rachel Funk, Tim McCoy | |
50% of the exterior surface has black/brown fusion crust with rust spots. The exposed surface is a brown/black color. The meteorite exhibits a black interior. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section shows an aggregate of chondrules (up to 1 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide. Chondrules contain minor abundances of olivine. Weathering is moderate. Microprobe analyses show the pyroxene is Fs1-3 and that the Fe,Ni metal contains 3 wt. % Si. The meteorite is an EH3 chondrite. |
