Figure F30. A. Reconstruction of small pillow based on three adjacent pieces. Note the glassy chilled margin on the top piece (green) covered by hyaloclastite containing angular green glass fragments (interval 195-1201D-48R-4, 12-26 cm). B. Long, relatively continuous piece of aphyric basalt exhibiting a glassy pillow margin on upper surface (interval 195-1201D-52R-1, 18-44 cm).
