Macroscopic Description - Kathleen McBride, Cecilia Satterwhite | |
The exteriors of these impact melts are fractured with dark brown to black fusion crust with oxidation haloes. The dark gray to black matrix is heavily oxidized with rust and metal. | |
Thin Section Description (,2) - Linda Welzenbach, Pamela Salyer, Tim McCoy | |
The section consists dominantly of individual clasts containing shocked chondrule fragments. Many of the silicates are mosaicized. Metal-sulfide melt textures are present, with most of the metal found in the veins between clasts. Veins are, for the most part, completely opaque. Olivine compositions are Fa23-28 and pyroxene is Fs20-21. These meteorites are shock blackened impact melt breccias of an L chondrite precursor. These meteorites are similar enough for an initial pairing, and are also similar to DOM 10440. |
