The Miocene Monterey Formation exposed along the cliffs of Upper Newport Bay represents a lower calcareous facies dominated by foraminifera and coccoliths, indicating warm climate and low nutrient waters, and a siliceous facies consisting of diatomaceous rocks, which records high productivity as a result of climatic deterioration and intensified upwelling.

We tested marine diatom transport to the Sirius Group by considering the microfossil distribution within one key glacial deposit in the dry valleys reported to contain Neogene marine diatoms: the Sirius Group at Mount Fleming (Harwood a) (figure 1).

The Cape Roberts Project (CRP) is an international drilling effort with the goals of recovering a tectonic and paleoenvironmental history of the Victoria Land Basin, Western Ross Sea, Antarctica. Diatomaceous sediments from the Miocene Monterey Formation in Santa Barbara County, California, were investigated to gain a better understanding of sedimentary processes, diatom paleoecology, and the paleoenvironmental significance of laminated organic-rich hemipelagites.
Sedimentary couplets and individual laminae from laminated intervals were described and classified to assess.
In the study area, the basement is commonly overlain by the transgressive, middle Miocene Lompico Sandstone and the overlying Monterey Formation.

Most of the recovered fauna derives from nine outcrop sections orFile Size: 21MB. - Early Oligocene siliceous microfossils were recovered in the upper. m of the CRP-3 drillcore. Although abundance and preservation are highly variable through this section, approximately siliceous microfossil taxa were identified, including diatoms, silicoflagellates, ebridians, chrysophycean cysts, and endoskeletal dinoflagellates.
The portions of the Monterey Formation (Miocene, California) most enriched in organic matter paradoxically do not represent the intervals of highest organic-matter production. Highest production rates dilute organic matter by other biogenic material and correspond to highly siliceous.

Diatoms accounted for ca. 97% of all biosiliceous particles at m (vs. % silicoflagellates and % radiolarians), and ca. 94% at m (vs. % silicoflagellates and % radiolarians).
