| 357-M0076A-1R-1,0 | 1 | 0.000 | Sediment | Basaltic breccia, carbonate matrix | Fragments angular shaped in a brown (10YR 8/2, 10YR 6/2) foraminifera-rich sandy carbonate matrix. Foraminifera (up to 1mm) are likely pelagic. Clasts are poorly to moderately sorted and slightly oriented. They include mostly basalts, dolerite, and | rare serpentinite. The basalts locally contain vesicles and show weathering on the surface (presence of brown oxides/hydroxides). The dolerite is moderately oxidized along the rim. Thin section at 28-31cm is almost fresh dolerite | slightly | 90 | Structures: Veins=0 -- No veins; Foliation=0 -- Massive | Slight alteration |
| 357-M0076A-1R-1,35 | 2 | 0.350 | Sediment | Polymict breccia, carbonate matrix | Mixed, unsorted breccia with a green matrix. The clasts are up to 2cm in size, subrounded and include basalt and dolerite. Thin section at 24-27cm is a fresh vesicular basalt clast in an orange carbonate matrix with broken foraminifera and palagonitic | alteration of glassy clasts. | 100 |
