Figure F12. Close-up photograph of volcaniclastic pebble breccias (Units 12 and 14) that separate the volcanic rocks in the upper part of Hole 1188A from volcanic rocks in the lower part. They are grain supported and consist of completely altered, white and light gray, aphyric clasts. White clasts are bleached (sulfate-clay altered) and gray clasts are (partially) silicified. Arrow = clast that is sparsely vesicular (Unit 14; Interval 193-1188A-14R-1, 105-113 cm).
