Figure F40. Photograph of fresh (interval 193-1191A-1R-1, 9.5-11.5 cm) to slightly altered (interval 193-1191A-1R-1, 12-18.5 cm) aphyric rhyodacite from the top part of Hole 1191A. The main stretching orientation of the vesicles is normal to the surface of the sample (interval 193-1191A-1R-1, 9-19 cm).
