Macroscopic Description - Kathleen McBride | |
The exterior surface has brown/black fusion crust with oxidation halos. The rust and black colored crystalline interior is fine grained with a high metal content. | |
Thin Section Description (,2) - Linda Welzenbach, Tim McCoy | |
The section shows an equigranular aggregate of enstatite, with abundant metal and sulfide. Weathering is moderate, with alteration along fractures. Microprobe analyses reveal pyroxene compositions of Fs0-1 and metal contains 1.2 wt.% Si. The section exhibits extensive evidence of post-formation heating, probably due to shock. Quenched metal-sulfide intergrowths are common and sulfides grade from, e.g., FeS to MnS in a complete range at their mutual boundary. The meteorite is an EL6 chondrite. |
