Macroscopic Description - Cecilia Satterwhite | |
This meteorite has 80% brown/black fusion crust on the exterior with heavily rusted areas. The interior is very rusty with some dark gray to black matrix visible. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
This very small section shows an aggregate of chondrules (up to 1.5 mm), chondrule fragments, and pyroxene grains in a matrix of abundant metal and sulfide. Weathering is extensive, with staining of enstatite grains and minor alteration of metal and sulfides. Microprobe analyses show the pyroxene is Fs0-3. The meteorite is a type 3 enstatite chondrite, probably an EH3. |
