Atomic-absorption spectrophotometry and instrumental neutron activation analysis were used to determine concentrations of SiO2, Al2O3, FeOt, MgO, CaO, Na2O, K2O, MnO, La, Ce,... -
(Table 1) Sr isotopes and chemical composition of DSDP Hole 61-462A basalts
Sixteen elemental abundances and 87Sr/86Sr ratio of the Nauru Basin basalt (Cores 75 to 90: sub-bottom depths 950 m to 1050 m) from Hole 462A have been determined by inductively... -
(Table 1) Mineralogy of veins in basalts at DSDP Hole 61-462A
Numerous veins are present in basalts recovered from Hole 462A, Leg 61 of the Deep Sea Drilling Project. Three mineral assemblages are recognized and stratigraphically... -
(Table 1) Carbon and lipids at DSDP Hole 61-462
The lipids of a Pliocene and a Cretaceous sample from Site 462 were analyzed to assess their source and diagenetic history. Judging from the distributions of the n-alkanes,... -

Six core-samples from DSDP/IPOD Site 462 in the Central Nauru Basin were examined for tetrapyrrole pigment content. Samples ranged from Pliocene to middle Cretaceous, and were... -
(Table 1) Lithology and total organic carbon at DSDP Hole 61-462
The solvent-extractable lipids of Sections 462-49-4 (lower Maestrichtian), 462-54-2 (Campanian), and 462-59-1 (Cenomanian), from the Nauru Basin, were investigated for aliphatic... -
(Table 1) Interstitial-water chemistry at DSDP Hole 61-462
Concentration gradients of Ca, Mg, K, Sr, and Li at Site 462, Leg 61, are linear with depth; large changes occur in the unsampled, low-porosity limestone-chert zone between 375... -
(Table 1) Mineralogy of sediments at DSDP Site 61-462
Two holes (462, 462A) were drilled at Site 462 in the Nauru Basin, within an area formed at a fast-spreading Pacific-plate boundary 145 to 155 m.y. ago. Forty-eight sediment... -

This study deals with the mineralogical variability of siliceous and zeolitic sediments, porcellanites, and cherts at small intervals in the continuously cored sequence of Deep... -
(Table 1) Geochemistry of basalts of Nauru Basin
Leg 61 of the Deep Sea Drilling Project (DSDP) was concerned with drilling a single continuously cored multiple re-entry hole at site 462 in the Central Nauru Basin (Fig. 1).... -
