Figure F103. Close-up photograph of a diffuse silica-anhydrite-clay vein network and patches, overprinting completely anhydrite-clay altered volcanic rock. Late anhydrite veins with white clay ± silica halos crosscut both the alteration and the vein network (Sample 193-1188A-13R-1 [Piece 9, 60-72 cm]; 106.90 mbsf).
