The basalt is made of highly altered, brownish glass. A few skeletal Ca-plagioclase crystals are scattered in the groundmass. Relict euhedral olivine pseudomorphs can be recognized. No pyroxenes can be recognized. Vesicles range up to 2-3 mm in diameter. Crystallinity increases downward. Intersertal to intergranular texture. Pale green dolomite-rich mud intercalated in the dolerite is observed in interval 650A-66X-2, 105-110cm.
