Figure F9. Core photographs. A. Interval 331-C0013E-6X-CC, 28–43 cm. a = heavily vesiculated glass, now devitrified to clay and minor Mg chlorite. b, c = monomictic breccias comprising clasts of hydrothermally altered pumice in silica. Note the jigsaw texture, which indicates minimal movement of clasts. d = interbedded gray hydrothermal mud. B. Interval 331-C0013E-6X-CC, 8–27 cm. e = block of polymictic volcanic breccia in devitrified lava. f, g = complete loss of original textures because of silicification.
