Weathered fusion crust covers 60% of this fragment. One striking feature of this stone is the heavily weathered fracture surface which contains a semi-rounded clast, 1.5 x 1.3 x 0.2 cm in dimension. This clast is white to light gray in color and coarse-grained. The interior is moderately weathered (heavy in areas), medium-gray in color, and contains numerous chondrules.
