Figure F9. Close-up photographs of typical lithologies encountered in Unit IV at Site 1259. A. Black submillimeter-scale laminated claystone with organic matter (interval 207-1259A-57R-1, 123–137 cm). Note concentrations of phosphatic streaks and nodules at 133.5 cm. B. Black submillimeter-scale laminated claystone with organic matter intercalated with olive-gray laminated limestone that is strongly cemented by calcite (interval 207-1259A-57R-2, 10–28 cm). C. Close up of black submillimeter-scale laminated claystone with organic matter that contains layers of white calcite (infilled foraminifers) (interval 207-1259A-59R-4, 6474 cm).
