(Table 1) Magnetic properties of basalt samples, at DSDP Legs 69 and 70
We studied magnetic properties of basalts from cores of Sites 504 (mainly Hole 504B) and 505. According to magnetic and petrographic data, the basalts are altered to different... -
(Table 1) Paleomagnetic properties of specimens from DSDP Holes 69-504B and 7...
Paleomagnetic and rock magnetic measurements of basalt specimens from DSDP Hole 504B, associated with the Costa Rica Rift, have a mean natural remanence intensity (Jn) between 5... -
(Table 1) Physical properties of basalts from DSDP Holes 69-504B and 70-504B
A detailed study of physical properties was made on core samples from Deep Sea Drilling Project Hole 504B. The measured properties are density, porosity, sonic velocity,... -
(Table 1) Compressional-wave and shear-wave velocities and elastic constants ...
Shear-wave and compressional-wave velocities of 26 basalt samples collected at Site 504 during Deep Sea Drilling Project Legs 69 and 70 were measured at elevated confining... -
(Table 1) Physical properties of basalts from DSDP Legs 69 and 70
Physical properties of basalts from Deep Sea Drilling Project Sites 504 and 505, south of the Costa Rica Rift, including wet-bulk density, water content, sonic velocity, and... -

Whole-rock basalt samples from the upper half of Deep Sea Drilling Project Hole 504B have oxygen-isotope compositions typical of mid-ocean-ridge basalts which have experienced a... -
(Table 1) Sulfur isotopes, total sulfur, and degree of oxidation of basalt sa...
About 150 basalt samples from Hole 504B, near the Costa Rica Rift were analyzed for sulfur content and sulfur-isotope composition. The basement in Hole 504B can be divided into... -
(Table 1) Sulfur and oxygen isotopes from two anhydrite samples recovered fro...
The first anhydrite reported from oceanic basalts occurs in altered basalts drilled during DSDP Leg 70 from Hole 504B. Anhydrite has been identified in several samples, two of... -
(Table 2) Dissolution rate of sediments at DSDP Site 70-506
Dissolution rates of calcareous ooze were measured for samples from Deep Sea Drilling Project (DSDP) Site 506, which is in the area of the Galapagos Spreading Center. Using the... -
(Table 7) Fe**3+/Fe**2+ ratios in selected nontronite samples at DSDP Leg 70 ...
Since its discovery in 1974 (Klitgord and Mudie, 1974), the Galapagos mounds hydrothermal field has received much attention. Sediment samples were taken during Leg 54 of the... -

Compressional- and shear-wave velocity logs (Vp and Vs, respectively) that were run to a sub-basement depth of 1013 m (1287.5 m sub-bottom) in Hole 504B suggest the presence of... -
(Table 1) Downhole variation of potassium, apparent K-Ar age, and inert gas a...
Ne, Ar, Kr, Xe, and K2O were measured in representative samples of holocrystalline basalt from DSDP Hole 504B. No hiatus in inert gas abundance is recognized at the base of the... -
(Table 1) Sulfur isotopes and description of anhydrite in DSDP Holes 70-504B ...
Anhydrite occurs in veins in hydrothermally altered basalts recovered from Hole 504B during Leg 83 of the Deep Sea Drilling Project. Sulfur isotopic data indicate that the... -
