https://www.pangaea.de/ information publisher tableDigital Supplement to: Blake, Gregg H (1981): Biostratigraphic implications of Neogene benthic foraminifers from Site 468, Southern California continental borderland: A preliminary study. In: Yeats, RS; Haq, BU; et al. (eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office), 63, 437-444, https://doi.org/10.2973/dsdp.proc.63.110.1981 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. completed Blake, Gregg H principalInvestigator DSDP Deep Sea Drilling Project theme 1995-01-01 creation PANGAEA
