doi:10.2204/iodp.proc.331.103.2011 BiostratigraphyCore catcher material from Site C0013 was processed for micropaleontological examination (Table T4). Samples consist of clay clasts (often producing a relatively large, fine-grained [<63 µm] sample of clay) and anhydrite, with smaller amounts of various sulfide minerals (euhedral pyrite > sphalerite > galena). Microfossils were not observed in any of these samples using light or electron microscopy. Samples that possessed a higher proportion of base metal sulfides were observed at 9.5 mbsf (millimeter-scale sphalerite), 12.6 mbsf, and 12.8 mbsf (1–5 mm sphalerite). Material was examined using scanning electron microscopy for mineralogical identification, as reported in “Petrology.” |
