| Black shiny and grey dacite. Banded from black cores with few large vesicles to sheared grey relatively devitrified rims. Sparsely phyric, with 1-2 small plagioclase phenocrysts per block. Locally a thin black MnOx dusting on surfaces. No glassy crust. | ||
| Grey aphyric dacite(?). As for 39-02, but lighter in color. Maybe the same flow. | ||
| Dark grey aphyric dacite(?). Cryptocrystalline groundmass with 10% small vesicles. Weathered MnOx encrusted (1-2 mm) surface. An old flow. |
