Figure F29. Downhole felsic vein intensity (vol%) averaged over every 10 m of core. Despite the scatter, the overall felsic vein abundance decreases with increasing depth. In the entire 1003.05 m of Leg 176 core, 203 felsic veins or sets of veins were recognized. The total accumulative length of the felsic veins is 5.43 m, which makes up ~0.54% of the total volume of the core recovered. Leg 118 data from the upper 500 m of Hole 735B are plotted for comparison (data from Dick et al., [1991a]). Presence of felsic veins in upper 70 m of the Leg 118 section is obscured by deformation (H. Dick, pers. comm., 1997).
