Plate 1. Hand-specimen photographs of representative breccia. In all figures, the scale bar is 1 cm, and the top of photographs is up-core. 1. Sample 161-976B-75R-1, 64-73 cm. Unsorted cataclastic breccia with angular clasts of high-grade schist. Observe clasts broken from single porphyroclasts, within a light-colored groundmass or matrix that fills a major fracture between larger metamorphic porphyroclasts. 2. Sample 161-976B-75R-1, 94-103 cm. Fine-grained breccia-groundmass and metamorphic porphyroclast in the left lower corner with dolomitic matrix (D) including foraminifer ghosts. 3. Sample 161-976B-105R-1, 130-144 cm. Fault gouge (right side) with a clay-rich groundmass and a very noticeable cataclastic foliation (S). 4. Sample 161-976E-17R-1, 119-126 cm. Dolomite-breccia similar to that shown in (2). Angular clasts are surrounded by light, narrow rims of nonplanar replacive dolomite (arrows). The breccia is cut by later, narrow white calcite veins. Note somewhat larger clasts concentrated on the top of the sediment-filled fracture. 5. Sample 161-976E-21R-2, 48-55 cm. Open fractures fill with laminated particulate sediments, showing convex-upward geometries (arrow). Notice that fracture wall can be fitted together. 6. Sample 161-976E-21R-2, 84-92 cm. Cataclastic cemented breccia with porphyroclasts of white marble (M) and schist. Click on image for enlargement.
