    In:  Supplement to: Miller, Kenneth G; Thomas, Ellen (1985): Late Eocene to Oligocene benthic foraminiferal isotopic record, Site 574, equatorial Pacific. In: Mayer, L; Theyer, E; et al. (eds.), Initial Reports of the Deep Sea Drilling Project, Washington (U.S. Govt. Printing Office), 85, 771-777, https://doi.org/10.2973/dsdp.proc.85.123.1985
    Publication Date: 2023-07-24
    Description: Oxygen and carbon isotopic data from mixed species of the benthic foraminifer Cibicidoides at Site 574 in the equatorial Pacific are compared with benthic foraminiferal isotopic data from equatorial Pacific Site 77 (Keigwin and Keller, 1984) and western North Atlantic Site 563 (Miller and Fairbanks, 1983, in press). Cibicidoides within the age range of about 33 to 35 Ma (within the early Oligocene) at the Pacific sites were lower in d13C than those of the same age from the North Atlantic site. For those from about 26 to 33 Ma (late early to late Oligocene), the equatorial Pacific and western North Atlantic d13C values were similar, whereas for those from about 26 to 12 Ma (latest Oligocene to Miocene) (see Miller and Fairbanks, 1983), Pacific values were lower. We suggest that this reflects bottom-water production analogous to modern North Atlantic Deep Water (NADW) in the early Oligocene and latest Oligocene to Miocene and reduced production of "NADW" in the late early to late Oligocene. High d18O values (approximately 2.0 per mil) were recorded at Site 574 for Cibicidoides at 36 Ma (earliest Oligocene); high, oscillating d18O values occurred from 30 to 29 Ma (near the early/late Oligocene boundary). These intervals of high d18O values apparently represent either bottom waters colder than at present or the presence of significant continental ice sheets. We suggest that major periods of continental glaciation occurred at approximately 36 and from 29 to 30 Ma.

    In:  Supplement to: Miller, Hubert; Loske, Werner; Kramm, Ulrich (1987): Zircon provenance and Gondwana reconstruction: U-Pb data of detrital zircons from Triassic Trinity Peninsula formation metasandstones. Polarforschung, 57(1/2), 59-69, hdl:10013/epic.29583.d001
    Publication Date: 2023-07-11
    Description: Morphological and U-Pb isotope studies on sedimentary zircons reflect the orogenic evolution of their former host rocks. The orogenic history of detrital zircons from the Trinity Peninsula Formation (TPF) defines the former geological surrounding of the sedimentation basin of the TPF. Same few weil rounded, polycyclic zircons of Precambrian age and Cambrian overprint give hints for an old cratonic source rock. Because of their very low frequency compared with euhedral types, the contribution of an cratonic shield area to the bulk of the sedimentary debris is neglectable low. Euhedral zircons of granitoid origin and Carboniferous age indicate a derivation from an area of widespread Carboniferous intrusions. Except for southern South America and unsurveyed regions in the Antarctic Peninsula itself, no region could deliver zircons with a Carboniferous age record. The only acceptable explanation for the origin of these zircons is a position of the Antarctic Peninsula during the sedimentation of the TPF approximately southwest of southern South America.

    Description: Baltimore Canyon Trough, the most intensely studied offshore sedimentary basin of the U.S. Atlantic margin, encompasses the coastal plain, continental shelf, and continental slope of New Jersey, Delaware, Maryland, and (in part) Virginia. On the basis of the extensive published record of the geological and geophysical investigations of this area, the New Jersey margin was chosen as the most suitable location for constructing the first marginwide stratigraphic transect. As envisioned, the transect would extend from the outcrop belt in central New Jersey to a location 700 km distant on the lower continental rise. Initial Deep Sea Drilling Project (DSDP) core holes on the slope and upper rise would emphasize the Cenozoic and Upper Cretaceous sections, as dictated by the limitations of openhole drilling. Leg 95 was principally intended to provide a crucial link between shelf and lower rise sites which had been cored along the transect during Leg 93.
