The onset of abundant ice-rafted debris (IRD) deposition in the Nordic Seas and subpolar North Atlantic Ocean 2.72 millions of years ago (Ma) is thought to record the Pliocene... -
(Table 1) Lead isotopic composition and concentration at DSDP Leg 82 Holes
The aim of DSDP Leg 82 was to decipher the temporal and spatial evolution of Azores Plume. The Pb-isotopic results of this leg are rather complex, and can be summarized as... -
(Table A1) Isotopic ratios of Sr, Nd, and Pb for sediments in ODP Leg 138 sites
The provenance of eolian dust supplied to deep-sea sediments has the potential to offer insights into changes in past atmospheric circulation. Specifically, measuring temporal... -
(Table 1) Sr, Nd, and Pb isotopic composition of ODP Leg 129 basalts
Basaltic rocks recovered from three drill sites in the western Pacific during Ocean Drilling Program Leg 129 have fairly distinct Sr, Nd, and Pb isotopic compositions. The... -
(Table 1) Isotopic and trace-element composition of ODP Leg 127/128 basalts
The western Pacific includes many volcanic island arc and backarc complexes, yet multi-isotopic studies of them are rare. Basement rocks of the Sea of Japan backarc basin were... -
(Table 1) Lead isotopic compositions of basalts from DSDP Hole 81-553
The passive continental margin south-west of Rockall Plateau is characterized by a thick sequence of oceanward-dipping seismic reflectors. During Leg 81 of the Deep Sea Drilling... -
(Table 1) Isotopic and trace-element ratios of Emperor Seamount basalts
When a mantle plume interacts with a mid-ocean ridge, both are noticeably affected. The mid-ocean ridge can display anomalously shallow bathymetry, excess volcanism, thickened... -

Lead isotopic compositions and Pb and Ba concentrations have been measured in ice cores from Law Dome, East Antarctica, covering the past 6500 years. 'Natural' background... -
Isotope ratios of basalts from ODP Leg 115 holes (Table 1)
Strontium, neodymium, and lead isotope ratios are reported for 13 Leg 115 basalts as well as 3 basalts from Texaco drill hole SM-1 on the Mascarene Plateau. The 87Sr/86Sr ratios... -
Tab. 1: Zircon isotopic data and rock ages from the Antarctic Peninsula
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... -
