(eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office) 63 https://doi.org/10.2973/dsdp.proc.63.110.1981 437-444 In recent years there has been considerable discussion concerning the biostratigraphic correlations between planktonic zonations and the classical Neogene California benthic foraminiferal stages. One of the primary objectives of IPOD Leg 63 was to investigate these correlations and to determine the possibility of temporal variation of the benthic stages between California land sections and the outer Continental Borderland. In addition, it was anticipated that analyses of the benthic foraminiferal faunas at Site 468 would provide critical information on the paleoenvironmental history of the outer borderland. The provincial benthic Neogene foraminiferal stages were established by Kleinpell (1938) for the Miocene and Natland (1952) for the Pliocene-Pleistocene; both are well-documented in designated type sections. These stages have been used for interbasinal correlations, although time-transgressive problems have been suggested by several authors (Bandy, 1971; Ingle, 1967, 1973; Crouch and Bukry, 1979). An important biostratigraphic sequence occurs at Site 468, significant because of its relatively shallow depth of approximately 1700 meters. The samples yield well-preserved benthic foraminiferal faunas throughout most of the Neogene sequence and are accompanied by abundant well-preserved calcareous and siliceous planktonic assemblages. It is this co-occurrence of both planktonic and benthic faunas that enables the correlation of outer continental margin sediments with those of the classical land-based sections of southern California. -120.1092 -120.1092 32.6235 32.6235 -120.1092 32.6235 1978-10-21T00:00:00 1978-10-21T00:00:00 -1737.0 -1737.0 not specified DSDP Deep Sea Drilling Project http://www.deepseadrilling.org/ Deep Sea Drilling Project DSDP 63-468A 32.6235 -120.1092 -1737.0 1978-10-21T00:00:00 35.5 m 27.7 m North Pacific/ESCARPMENT Leg63 https://doi.org/10.2973/dsdp.proc.63.1981 Yeats, Robert S 1978-10-09 1978-11-26 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 4 cores; 35.5 m cored; 0 m drilled; 78 % recovery 63-468B 32.6235 -120.1092 -1737.0 1978-10-21T00:00:00 415.5 m 103.1 m North Pacific/ESCARPMENT Leg63 https://doi.org/10.2973/dsdp.proc.63.1981 Yeats, Robert S 1978-10-09 1978-11-26 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 37 cores; 351.5 m cored; 0 m drilled; 29.3 % recovery 54 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Event label Event Event Sample code/label Sample label DSDP/ODP/IODP sample designation hdl:10013/epic.27914.d001 Blake Gregg H Sample label Foraminifera, planktic/benthic ratio Foram plankt/bent Foraminiferida https://www.marinespecies.org/aphia.php?p=taxdetails&id=22528 Foraminifera https://www.marinespecies.org/aphia.php?p=taxdetails&id=1410 benthic ratio Blake Gregg H Foram plankt/bent supplement citable author48780 basis12 campaign185 event12685 event12686 geocode1599 geocode1600 geocode1601 geocode8128 inst41 license101 method10974 method5059 param2203 param790 pi48780 project4 ref60324 term1045523 term1755587 term20800 term2663825 term48984 topotype1
