Preliminary correlation and age of rock samples (KG-1 to KG-24) in the Cooperative Monterey Organic Geochemistry Study, Santa Maria and Santa Barbara-Ventura basins, California

Supplementary data on diatoms and calcareous nannofossils and preliminary revised ages for rock samples (KG-1 to KG-24) in the Cooperative Monterey Organic Geochemistry Study, Santa Maria and Santa Barbara-Ventura basins, California

“…Age assignment: 8.7-7.8 Ma. Comments: The diatom age assignment here is inconsistent with preliminary physical correlation both to the Arends-Blake zonation of Naples (Arends and Blake, 1986) and to the DePaolo-Finger section at Naples (DePaolo and Finger, 1991) as discussed in Preliminary Correlation and Age (Isaacs, Tomson, Lewan, Arends, Cotton, and Filewicz, 1992) and is accordingly disregarded. The diatom Thalassiosira antiqua, which should be present if this sample belongs to the Thalassiosira antiqua zone, was not observed.…”

“…Age assignment: none. Comments: This sample was tentatively assigned an age of 5.1-6.1 Ma in Preliminary Age and Correlation (Isaacs, Tomson, Lewan, Arends, Cotton, and Filewicz, 1992 Very good preservation, looks like a relatively pure diatomaceous ooze that underwent little or no bioturbation or post-depositional transport. The sample was deposited during a relatively warm period and is dominated by planktonic taxa.…”
