Pore-water chemistry of ODP sites 111-677 and 111-678
Sites 677 and 678 were drilled on ODP Leg 111 to test hypotheses about the nature and pattern of hydrothermal circulation on a mid-ocean ridge flank. Together with earlier... -
Seismic properties of sheeted dikes from ODP Hole 111-504B
Seismic velocities have been measured at confining pressures to 600 MPa for eight samples of sheeted dike rock obtained from Hole 504B during Leg ODP 111. The compressional- and... -
Magnetic properties and oxide petrography of ODP Hole 111-504B
Magnetic properties measurements were performed on 47 samples drilled during Leg 111 of the Ocean Drilling Program and oxide petrography was studied in 32 samples taken at... -
Calcium carbonat content and stratigraphic correlation of ODP Leg 111 sites a...
The recovery of continuous sedimentary sequences has been and is a high-priority goal of the Ocean Drilling Program, yet its success has not been determined. We test the... -
Organic properties of sediments and amino acids in iterstitial waters of ODP ...
The basement at Ocean Drilling Program (ODP) Sites 677 and 678 originated from the Galapagos spreading center of the Costa Rica Rift and has moved about 200 km over the last 6... -
REE, Ba, and Sr abundances and Sr, Nd, and Ce isotope ratos of ODP Hole 110-5...
Abundances of rare earth elements (REE), Ba, and Sr and isotopic ratios of Sr, Nd, and Ce were determined for six samples of basalts drilled at Hole 504B on Leg 111 of the Ocean... -
Chemistry of various minerals of altered basalts from ODP Hole 111-504B
Basalts recovered from Hole 504B during ODP Leg 111 are more or less altered, but there is no sign of strong shear stress or widespread penetrative deformation; hence, they... -
Chemistry of basalts of ODP Hole 111-504B
The effect of oxygen fugacity (fO2) on the partition relationship of Mg and Fe between Plagioclase and sillicate liquid was investigated at 1 atm for basaltic samples recovered... -
Petrology and isotope characteristics of basalts from ODP Hole 111-504B
Petrography and isotope geochemical characteristics of H, O, S, Sr, and Nd have been described for basalts recovered from Hole 504B during Leg 111 of the Ocean Drilling Program.... -
Radiolarian biostratigraphy of ODP Site 111-677
Well-preserved late Miocene through Pleistocene age radiolarian assemblages were recovered during ODP Leg 111 at Site 677, on the southern flank of the Costa Rica Rift in the... -
Late Miocene to Pleistocene planktonic foraminifera of ODP Site 111-677
Forty-three core-catcher samples from the upper Miocene to uppermost Pleistocene of ODP Site 677 were examined for planktonic foraminifers. Range charts were compiled for Holes... -
Geochemistry of the oceanic crust from ocean drilling samples
This book presents new data on chemical and mineral compositions and on density of altered and fresh igneous rocks from key DSDP and ODP holes drilled on the following main... -
Lithium concentrations and isotope composition of basalt samples from ODP/DSD...
Ocean Drilling Program (ODP) Hole 504B near the Costa Rica Rift is the deepest hole drilled in the ocean crust, penetrating a volcanic section, a transition zone and a sheeted... -
Mineralogy, chemistry and stable isotope composition of hydrothermal altered ...
During ODP Leg 111 Hole 504B was extended 212 m deeper into the sheeted dikes of oceanic Layer 2, for a total penetration of 1288 m within basement. Study of the mineralogy,... -
Strontium chemistry of anhydrite from DSDP/ODP Hole 504B
A unique record of the chemical evolution of seawater during hydrothermal recharge into oceanic crust is preserved by anhydrite from the volcanic sequences and sheeted dike... -
Age and oxygen isotope data for bulk carbonate from DSDP Sites 41-366 and 72-...
A numerical model which describes oxygen isotope exchange during burial and recrystallization of deep-sea carbonate is used to obtain information on how sea surface temperatures... -
3He/4He and 4He/20Ne ratios in pore water and gas in Pacific deep-sea sediments
We have measured the 3He/3He and 3He/20 Ne ratios of thirty-nine pore water and gas samples in deep-sea sediments collected at twelve sites on the Pacific Ocean bottom during... -
Benthic foraminiferal stable isotope record from ODP Site 138-849 on the East...
Benthic foraminifer and delta13C data from Site 849, on the west flank of the East Pacific Rise (0°11 'N, 110°31'W; 3851 m), give relatively continuous records of deep Pacific... -
