WG-6-2

The specimen is a domical wedge with curved marginal fractures beneath the anterior edge. A thin (≤1 mm), dark grey to black, glassy fusion crust covers ±70% of the surface, including the anterior and basal/posterior areas. The anterior displays radiating melt streaks, while the posterior shows thicker, high-gloss black glass with dimpled texture and sinuous, anastomosing melt "ribs." Lithologically, it is a polymict breccia with a fine-grained light grey-green matrix with minor opaque phases, and coarser-grained clasts. The clasts include an ~3 × 1 cm lozenge-shaped lithic fragment with fine-grained mineralogy, small (1-5 mm) black aphanitic basaltic fragments, and larger (≤1 cm), dark grey-green, polymineralic clasts, and minor opaques. There are dark grey-green clasts (≤1 mm) that represent mono- or polymineralic lithic fragments.
