Magnetic properties of basalts at DSDP Hole 83-504B
We have studied the magnetic properties of 22 samples from DSDP Leg 83 to determine the origin of remanence and its relationship to such problems as the tectonic and chemical... -
Magnetic properties, grain sizes and minerals at DSDP Site 83-504B
Twenty-seven samples from the Leg 83 section of Hole 504B have been investigated using magnetic, optical, and electron optical methods. The primary magnetic mineral to... -
Magnetic properties and heavy metals at DSDP Hole 83-504B
We report measurements of magnetic intensity, inclination, initial susceptibility, Koenigsberger's ratio, saturation magnetization, and Curie temperatures of 68 basalt samples... -
Geochemistry, isotopes, trace elements and fluid inclusion geothermometry at ...
Stockwork-like metal sulfide mineralizations were found at 910-928 m below seafloor (BSF) in the pillow/dike transition zone of Hole 504B. This is the same interval where most... -
Geochemistry and fluxes at DSDP Hole 83-504B
This chapter documents the chemical changes produced by hydrothermal alteration of basalts drilled on Leg 83, in Hole 504B. It interprets these chemical changes in terms of... -
Major oxides, trace elements and rare earth elements of selected basalt sampl...
DSDP Hole 504B is the deepest section drilled into oceanic basement, penetrating through a 571.5-m lava pile and a 209-m transition zone of lavas and dikes into 295 m of a... -
Petrology of basalts from DSDP Hole 83-504B
Basalts from Hole 504B, Leg 83, exhibit remarkable uniformity in major and trace element composition throughout the 1075.5 m of basement drilled. The majority of the basalts,... -
Selective destructive demagnetization of breccias from DSDP Hole 83-504B
The magnetization of four breccia samples from the Leg 83 section of DSDP Hole 504B was analyzed by selective destructive demagnetization in order to study the origin and... -

DSDP Hole 504B is the deepest basement hole in the oceanic crust, penetrating through a 571.5 m pillow section, a 209 m lithologic transition zone, and 295 m into a sheeted dike... -
Strontium, oxygen and hydrogen isotope ratios of basalts from DSDP Hole 504B
DSDP Hole 504B was drilled into 6 Ma crust, about 200 km south of the Costa Rica Rift, Galapagos Spreading Center, penetrating 1.35 km into a section that can be divided into... -
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... -
Geochemistry, and Nd- and Pb-isotopic composition of basalts from the upper o...
The DSDP/ODP Hole 504B, drilled in the 5.9 Ma southern flank of the Costa Rica Rift, represents the deepest section through modern ocean floor basaltic basement. The hole... -
