Figure F80. Macroscopic character of veins, Hole U1415J. A. Irregular prehnite vein (red arrow) perpendicular to magmatic foliation typical of the upper half of Hole U1415J in Units I and II (Sample 345-U1415J-8R-1A, 88.5–106 cm [Piece 14]). B. Set of parallel chlorite (greenish) veins perpendicular to the vertical magmatic foliation and set of parallel prehnite (white) veinlets (red arrows) parallel to the vertical magmatic foliation. Note branching of some vertical prehnite veins into horizontal chlorite veins (Sample 345-U1415J-18R-1A, 137.5–147 cm [Piece 17]).
