Figure F110. A. Photomicrograph of vein network and jigsaw-fit breccia in altered, flow-banded volcanic rock. The veins contain quartz, anhydrite, sphalerite and pyrite (Unit 23; Sample 193-1189B-14R-1 [Piece 15, 106-118 cm] at 157.57 mbsf). B. Sketch of A. Black = sulfides and gray = anhydrite and quartz. Prominent flow bands are marked A to G. For explanation, see "Breccias and Vein Network Structures," .
