Barium intensities and tie points between holes of Leg 208
The Paleocene - Eocene thermal maximum (PETM) is one of the best known examples of a transient climate perturbation, associated with a brief, but intense, interval of global... -
Chemical composition of Late Cenozoic volcanic and volcaniclastic deposits fr...
Tephra fallout layers and volcaniclastic deposits, derived from volcanic sources around and on the Papuan Peninsula, form a substantial part of the Woodlark Basin marine... -
Geochemistry and stratigraphy on sediment cores from Leg198 and Leg 208
The first complete cyclic sedimentary successions for the early Paleogene from drilling multiple holes have been retrieved during two ODP expeditions: Leg 198 (Shatsky Rise, NW... -
Mineralogy and geochemistry of Mg-phyllosilicates from Middle Valley, norther...
We present results of a detailed mineralogical and geochemical study of the progressive hydrothermal alteration of clastic sediments recovered at ODP Site 858 in an area of... -
Petrology and geochemistry of sideromelane glass shards from Pleistocene as l...
Major elements, S, F, Cl concentrations and relative proportions of S6+ to total S were analyzed with electron microprobe in sideromelane glass shards from Pleistocene... -
Composition, oxygen isotope and crystallisation temperature of clay samples f...
Oxygen isotopic compositions of clay minerals were determined on representative samples of the volcano-sedimentary series from Site 841 ODP (Tonga forearc). This isotopic study... -
Element analyses and isotope composition of basalts from the West Valley segm...
The 50 km-long West Valley segment of the northern Juan de Fuca Ridge is a young, extension-dominated spreading centre, with volcanic activity concentrated in its southern half.... -
Element analyses and isotopic composition of basalts from the western Pacific
New Sr- Nd- and Pb-isotopic and trace element data are presented on basalts from the Sulu and Celebes Basins, and the submerged Cagayan Ridge Arc (Western Pacific), recently... -
Recent ostracods in surface sediment samples from Admiralty Bay, King George ...
Ostracods from Admiralty Bay on King George Island (South Shetland Islands) represent 29 podocopid species, belonging to 19 genera, one cladocopid and six myodocopid species.... -
Major element composition of phenocrysts from the volcanic basement of ODP Ho...
Early arc volcanism during Eocene to Oligocene in the Izu forearc region was investigated during ODP Legs 125 and 126 in 1989, and effusive and intrusive volcanics were... -
Fine-silt luminescence dating and mineral composition of sediments from the A...
New geochronometers are needed for sediments of the Arctic Ocean spanning at least the last half million years, largely because oxygen-isotope stratigraphy is relatively... -
Element and isotope composition of selected volcanics from the Bicol arc, Phi...
Pliocene to recent volcanic rocks from the Bulusan volcanic complex in the southern part of the Bicol arc (Philippines) exhibit a wide compositional range (medium- to high-K... -
Sedimentology and geochemistry of Oxygen Isotope Stage 3 and Holocene sedimen...
Seismic reflection studies in the maar lake Laguna Potrok Aike (51°58? S, 70°23? W) revealed an erosional unconformity associated with a sub-aquatic lake-level terrace at a... -
Sedimentology and geochemistry of late glacial and Holocene sediments from La...
A high-resolution multiproxy geochemical approach was applied to the sediments of Laguna Potrok Aike in an attempt to reconstruct moist and dry periods during the past 16 000... -
Sedimentology of cores from the continental rise west of the Antarctic Peninsula
The continental rise west of the Antarctic Peninsula includes a number of large sediment mounds interpreted as contourite drifts. Cores from six sediment drifts spanning some... -
Magnetostratigraphy of sediment cores from the eastern Arctic Ocean
A new high-resolution magnetostratigraphic record from the eastern Arctic Ocean has yielded further evidence for the existence of the Laschamp excursion (37–35 ka), the Mono... -
