Macroscopic Description - Kathleen McBride | |
The exterior has brown crust with large rust haloes. The interior is rusty and fine-grained with high metal content. It exhibits a dull and powdery texture and is hard. Light colored clasts/chondrules stained with rust are visible within the matrix. | |
Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach, Nicole Lunning | |
This meteorite section consists of equigranular crystals (up to 0.5 mm) of polysynthetically twinned enstatite, feldspar, iron-nickel metal, sulfides, daubreelite, niningerite, and alabandite. Texturally, this meteorite is similar to, though much less weathered than, Happy Canyon. This meteorite is an enstatite chondrite impact melt. |
