| Macroscopic Description - Kathleen McBride | |
| The exterior has 10% brown/black fusion crust. The black and white crystalline matrix has large 3-7 mm sized chondrules, rusty and gray in color. | |
| Thin Section Description (,2) - Tim McCoy | |
| The section consists of subequal amounts of metal and sulfide. Metal occurs as rounded particles up to 4 mm in diameter. Chondrules and chondrules fragments up to 0.5 mm are dominated by radiating pyroxene textures with olivine present. Silicates are magnesian (Fa1-3, Fs1-3). The meteorite is similar to the bencubbinite/CB chondrites and resembles Gujba in some respects (Weisberg et al., 2002, LPSC XXXIII, #1551). | |
