Oxygen isotope composition, organic carbon content, and grain size distributi...
A high-resolution chronostratigraphy was established for Holes 680B and 686B, drilled during Ocean Drilling Program (ODP) Leg 112 off Peru. The stratigraphy is largely based on... -
Late Neogene to Pleistocene palynology of ODP Leg 112 samples
The main objectives of this study are (1) to characterize the spatial and temporal variations in organic matter deposited in upwelling and related sediments (manifest in the... -
Biochemical, geochemical and sedimentological study of ODP Leg 112 samples
Organic-rich diatomaceous muds from Ocean Drilling Program Leg 112 (offshore Peru) are the subject of a comprehensive organic diagenetic study covering the burial interval,... -
Geochemistry of carbonate cements of ODP Leg 112 samples
The evolution of pore fluids migrating through the forearc basins, continental massif, and accretionary prism of the Peru margin is recorded in the sequence of carbonate cements... -
Clay mineralogy of Cenozoic sediments from the Peruvian continental margin
Analysis of the clay mineralogy of 537 samples from Cenozoic sediments of the Peruvian forearc reveals distinctive geographic and stratigraphic patterns in the distribution of... -
Quaternary through early Eocene benthic foraminifera off Peru
Stratigraphic assemblages of Quaternary through early Eocene benthic foraminifers were recovered among 10 Peru margin drill sites. Various hiatuses and intervals barren in... -
Eocene through Pleistocene planktonic foraminifera off Peru
Planktonic foraminifers were studied from 213 samples collected during Leg 112 at 10 sites located on the continental shelf and slope off Peru. Because planktonic foraminifers... -
Tertiary and Quaternary calcareous nannoplankton biostratigraphy of ODP Leg 1...
Positions of all cores recovered during Ocean Drilling Program (ODP) Leg 112 off Peru are shown in the standard calcareous nannoplankton zonation. Stratigraphic and regional... -
Silicoflagellates, actiniscidians, and ebridians of ODP Leg 105 sites
Neogene and Quaternary silicoflagellates, actiniscidians, and ebridians are described from Sites 679 through 688 in the eastern Pacific off Peru. Five silicoflagellate zones and... -
Global data compilation of benthic data sets II
In this study we present a global distribution pattern and budget of the minimum flux of particulate organic carbon to the sea floor (J POC alpha). The estimations are based on... -
Radiolarian abundances of ODP Leg 112 holes
The radiolarian fauna found at the 10 sites drilled during Ocean Drilling Program (ODP) Leg 112 range in age from Eocene to Holocene. Relatively abundant and well-preserved... -
Carbonate cement mineralogy, isotope composition, and pore water environment ...
On the shelf and upper slope off Peru the signal of coastal upwelling productivity and bottom-water oxygen is well preserved in alternately laminated and bioturbated... -
Sulphur contents and partition of iron in ODP Leg 112 sediments
Porewaters in site 680 Peru Margin sediments contain dissolved sulfide over a depth of approximately 70 m which, at a sedimentation rate of 0.005 cm/yr, gives a sediment... -
Bromine and iodine concentrations in sediments and pore fluids of ODP Leg 112
At the Peruvian convergent margin, two distinct pore fluid regimes are recognized from differences in their Cl- concentrations. The slope pore fluids are characterized by low... -
Contents, partition, and isotopic composition of sulphur in sediments from OD...
We have determined (1) the abundance and isotopic composition of pyrite, monosulphide, elemental sulphur, organically bound sulphur, and dissolved sulphide; (2) the partition of... -
Carbon and Sulphur concentrations of sediments from Peru, Oman and Benguela u...
Abundances of organic carbon, sulfur, and reactive iron in sediments of three upwelling environments (Peru, Oman and Benguela) suggest that organic carbon/reduced sulfur ratios... -
