Figure F40. Close-up photographs of core sections illustrating crosscutting relationships between different generations of veins in Hole 1268A. A. Early pyrite-hematite vein network is crosscut by later talc-pyrite vein (interval 209-1268A-3R-2, 102–116 cm). B. Pyrite-hematite vein (arrowed) fading as it approaches a zone of talc alteration (interval 209-1268A-3R-2, 124.5–130 cm). C. Ghost pyrite-hematite veins fading in proximity to late talc alteration. A serpentine vein system is developed subparallel to the leading edge of the talc alteration front (interval 209-1268A-3R-2, 96–100 cm). D. Late massive talc vein crosscutting and offsetting earlier talc-pyrite veins. This relationship suggests that the emplacement of the massive talc vein was synchronous with normal faulting (interval 209-1268A-11R-1, 126–136 cm).
