Figure F9. Close-up photographs of representative lithologies encountered in stratigraphic Unit II. A. Multicolor basalt breccia in Subunit IIA (interval 330-U1372A-4R-3A, 3–43 cm). B. Foraminiferal limestone with inoceramid shell fragments and basalt clasts in Subunit IIB (interval 330-U1372A-5R-1A, 1.5–41.5 cm). Uppermost section includes ferromanganese encrustations on limestone and basalt, which suggest a long period without sedimentation. The Subunit IIB/IIC boundary is at 34 cm. The uppermost part of Subunit IIC is composed of a large basalt clast or lava flow. C. Multicolor basalt breccia in Subunit IIC (interval 330-U1372A-5R-3A, 57.5–97.5 cm). D. Fine-grained multicolor basalt conglomerate in Subunit IID (interval 330-U1372A-6R-3A, 42–82 cm). Basalt grain sorting is distinctively better in this subunit. E. Bluish-gray basalt conglomerate with bioclasts in Subunit IIE (interval 330-U1372A-8R-1A, 13.5–53.5 cm). This subunit contains distinctively larger, less altered basalt boulders and more bioclasts.
