Figure F111. Vein network and brecciated, highly silicified volcanic rock. The veins consist of quartz, magnetite, and pyrite. In the right upper part of the piece, at 19 cm, a thin anhydrite vein (white) can be seen crosscutting the quartz-magnetic-pyrite vein network (Section 193-1189B-16R-1 [Piece 3, 16-26 cm]; 175.85 mbsf).
