The meteorite is dominated by a fine-grained texture with olivine and pyroxene grains and chondrule fragments ranging up to 200 microns in diameter. The matrix contains abundant fine-grained (dominantly less than 25 microns in diameter) metal-troilite intergrowths with concave boundaries between the two phases, suggestive of rapid cooling. Silicates are homogeneous with olivine of Fa18 and orthopyroxene of Fs16. The meteorite appears to be a shock or impact melt from an H chondrite.
