Quaternary foraminiferal bio- and isotope stratigraphy of ODP Holes 122-760A and 122-762B, Exmouth and Wombat Plateaus, northwest Australia

Journal Article


Abstract


  • The bio- and isotope biostratigraphy of the uppermost (Quaternary) section at ODP Sites 122-760A and 122-762B are presented. Biozonations of Bolli and Premoli Silva (1973) and Chaproniere (1985, 1991) are recognized, as well as a distinctive acme in pink-pigmented forms of Globigerinoides ruber in the Late Pleistocene (isotope stages 5e to ~10). These, together with a series of sinistral-coiling events in Pulleniatina spp. and Globorotalia truncatulinoides during the Middle and Early Pleistocene, serve as locally useful bioevents in this part of the eastern Indian Ocean. The biostratigraphy indicates the presence of minor and major hiatuses, the latter associated with physical anomalies near 7 m downcore in Hole 760A and between 4 and 4.5 m in Hole 762B. -Authors
