Macroscopic Description - Kathleen McBride | |
Smooth brown/black fusion crust with oxidation haloes covers the exterior of this meteorite. It has a rusty crystalline interior with a high metal content intermingled with small patches of gray matrix. | |
Thin Section Description (,2) - Tim McCoy, Linda Welzenbach | |
The section is a breccia composed of angular isolated grains up to 1.5 mm and clasts of orthopyroxene (Fs30Wo2), anorthitic feldspar, metal (with included tetrataenite and schreibersite), troilite and oxides. The meteorite appears to be an isolated clast from a mesosiderite. |
