Figure F97. A. Variation in vein intensity with depth in Hole 735B. The scale is taken from the intensity scale as described in "Structural Geology" in the "Explanatory Notes" chapter, and is based on vein density. Data from Leg 118 have been included and scaled to match the data from Leg 176. The Leg 176 values are averaged over 31 structural intervals. The dashed, horizontal lines mark the positions of major faults; the solid, horizontal line marks the position of the major ductile shear zone. B. Variation in vein dip with depth in Hole 735B (N = 3245).
