Figure F11. Close-up photographs of infill structures in stratigraphic Unit II (Subunits IIA and IIC). A. Normal grading on top of large basalt clast (Subunit IIA; interval 330-U1372A-4R-2A, 89–99 cm). B. Geopetal structure at base of large basalt clast, indicating infilling by hemipelagic and volcaniclastic sedimentation after initial deposition of large basalt clasts (Subunit IIC; interval 330-U1372A-5R-5A, 39–49 cm).
