Figure 5. Basement sections in Holes 976B and 976E showing recovery and sampled metamorphic rock types (from Shipboard Scientific Party, 1996b). Main intervals of brittle deformation (breccia and fault-gouge intervals) deduced from core description and logging characteristics are indicated by shaded bands on the right-hand side of each lithologic column (from Comas and Soto, Chap. 25, this volume).
