Macroscopic Description - Kathleen McBride | |
Thick black fusion crust with bubbles covers this ureilite’s exterior surface. The interior is rusty black and fine grained with high metal content. | |
Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach, Pamela Salyer | |
The section consists of an aggregate of large olivine and pyroxene grains up to 2 mm across. Metal within the section occurs in very small grains (5 microns) and is evenly distributed throughout the olivine. Carbon veins are discontinuous (olivine grains are not completely surrounded by matrix carbon). The whole section has been mosaicized by shock. Olivine composition is Fa20-24. Pigeonite (Fs18,Wo4-5). The meteorite is a shocked ureilite similar to GRA 98032. |
