Macroscopic Description - Cecilia Satterwhite | |
The exterior has black fusion crust with some evaporites. The interior is black with visible metal grains. A few chondrules are also visible. | |
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. Weathering is modest, with staining of some enstatite grains and minor alteration of metal and sulfides. Microprobe analyses show the pyroxene is Fs0-1. Metal contains ~2.5 wt. % silicon. The meteorite is an EH4 chondrite. |
