Geochemistry of ODP Leg 115 basalts
Melting-phase relations at high pressures and Sr-Nd isotopic compositions are reported for basalts collected from the western Indian Ocean during Ocean Drilling Program Leg 115.... -
Carbonate composition of Pliocene-Pleistocene sediments of the Maledives
Ocean Drilling Program (ODP) Leg 115 post-cruise research was focused on two Maldives sites, more precisely on the top 108 m of Hole 716B (water depth, 540 m), equivalent to the... -
Quaternary and Paleogene calcareous nannofossils of ODP Leg 115
The occurrences of ten datum events for the Quaternary and top Pliocene nannofossils are identified at nine Leg 115 sites. A quantitative investigation of Paleogene nannofossils... -
Geochemistry of Neogene sediments of ODP Hole 115-711A
Pelagic sedimentation in the northwest Indian Ocean has been studied using sediments from Hole 711A (the section from 0 to 70.5 mbsf, 0-22 Ma), a deep site (4428 m) drilled... -
Carbonat-free sediment components of ODP Leg 115 holes
From the equatorial Indian Ocean, carbonate-free portions of sediment samples of Paleocene to Miocene calcareous oozes and chalks from Sites 707, 709, and 711 were studied using... -
Planktonic foraminifera and sedimentology of ODP Hole 115-708A
Pleistocene and Pliocene sediments from the top five cores of Hole 708A, western Indian Ocean, were subsampled to compare the degree of carbonate dissolution in pelagic and... -
Cd/Ca ratios and element analyses of ODP Hole 115-709C
During three to four d18O cycles (determined on Globigerinoides ruber), more positive d18O (= higher global ice volume) values correlated with higher Globorotalia menardii... -
Late Oligocene through early Pleistocene calcareous nannofossils of ODP Leg 1...
The chronostratigraphy, the calcareous nannofossil biochronology, and the biostratigraphy of the Miocene and Pliocene sediments retrieved during Leg 115 in the equatorial... -
Stable carbon and oxygen isotope record of planktonic foraminifera of ODP Hol...
A closely spaced (5-cm interval) oxygen isotope stratigraphy of planktonic foraminifers from Hole 709C was completed for most of the Pliocene and lowermost Pleistocene (around... -
Miocene benthic foraminifer oxygen and carbon isotope record of ODP Site 115-709
The benthic isotopic record of Miocene Cibicidoides from Site 709 provides a record of conditions in the Indian Ocean at a depth of about 3200 mbsf. As expected, the record... -
Late Cenozoic carbonate accumulation rates of ODP Leg 115 samples
The principal paleoceanographic objective of Ocean Drilling Program Leg 115 was to collect a suite of materials that would allow reconstruction of the dynamic features of the... -
Carbonate concentrations of ODP Leg 115 samples
We measured carbonate concentrations in Pleistocene and Pliocene sediments deposited at Sites 709, 710, and 711. Carbonate concentrations exhibit low-amplitude, long-wave length... -
Petrography, chemistry and magnetic properties of ODP Leg 115 basalts
A detailed study of the Fe-Ti oxides in four basalt samples-one from each of the four holes drilled into basement on Ocean Drilling Program Leg 115 (Sites 706, 707, 713, and... -
Primary mineralogy of ODP Leg 115 basalts
Basement rocks were recovered at four sites on Leg 115 along the Reunion hotspot track in the western Indian Ocean. Plate tectonic reconstructions indicate that the drilled... -
Eocene-Oligocene diatoms in the western Indian Ocean
The occurrence of diatom species in the Eocene-Oligocene sections of Ocean Drilling Program (ODP) Leg 115 sites and Deep Sea Drilling Project (DSDP) Sites 219 and 236 in the... -
Radiolarian biostratigraphy in the central Indian Ocean
Identifiable radiolarians of stratigraphic importance were recovered at eight of the sites drilled on Leg 115. The assemblages range in age from Holocene to middle Eocene... -
Eocene-Oligocene calcareous nannofossils from ODP sites 115-711 and 120-748 i...
An Eocene-Oligocene calcareous nannofossil biostratigraphic framework for Ocean Drilling Program (ODP) Site 748 in the southern Indian Ocean is established, which provides a... -
Geochemistry of Indian Ocean tephra and Afro-Arabian lavas
Widespread silicic pyroclastic eruptions of the Oligocene Afro-Arabian flood volcanic province (ignimbrites and airfall tuffs) produced up to 20% of the total flood volcanic... -
Chemical composition of basalts from ODP Leg 115
Leg 115 of the Ocean Drilling Program recovered basalts from four locations along the hotspot track that leads from the Deccan flood basalts in India to Reunion Island in the... -
Age models and stable isotope ratios from the Mid-Miocene
Mid-Miocene pelagic sedimentary sections can be correlated using intermediate and high resolution oxygen and carbon isotopic records of benthic foraminifera. Precision of a few...
