Figure F5. Core photographs of hydrothermal lithoclasts. A. Subrounded grains of sphalerite with minor anhydrite and pyrite grains (interval 331-C0013E-1H-4, 106–138 cm). B. Oblate sphalerite grains with euhedral anhydrite overgrowths (bottom right) (interval 331-C0013E-1H-4, 106–138 cm). C. Rounded, near-spherical hydrothermal lithoclast of sphalerite and quartz (interval 331-C0013E-1H-5, 75 cm).
