Figure 21. Basaltic breccia (?hyaloclastite) with individual clasts surrounded by light-colored vein material. Individual clasts consist of similar basaltic material without vesicles or phenocrysts. Alteration has destroyed most of the primary mineralogy (Subunit IVB, Hole 899B; Interval 149-899B-26R-1, 113.5-125 cm).
