Macroscopic Description - Cecilia Satterwhite | |
The exterior is dull brown/black with rusty areas. The interior is a rusty brown/black. | |
Thin Section Description - Tim McCoy, Lauren LaCroix, Linda Welzenbach | |
The section shows an aggregate of chondrules (up to 2.5 mm), chondrule fragments, and pyroxene grains in a matrix rich in metal and sulfide. Chondrules contain moderate to small abundances of olivine. Microprobe analyses show the olivine is Fa0-1 and pyroxene is Fs0-2. The meteorite is a type 3 enstatite chondrite, probably an EH3. |
