Geochemistry and isotopes at DSDP Site 68-503
Nodules occur in the siliceous calcareous ooze and siliceous marl at Site 503 in the eastern equatorial Pacific. They are present below a depth of about 11 meters throughout the... -
Chemistry of pore water and solids, formation factors and salt-corrected poro...
Recent discoveries relating to the circulation of fluids within the oceanic crust include the finding of both important fluxes of elements and isotopes into the oceans by... -
CaCO3, density, sedimentation and accumulation rates at DSDP Hole 68-503B
Pelagic sediments from DSDP Hole 5O3B contain, in their carbonate abundance data, a clear record of glacial-interglacial cycles. The eolian component of those sediments was... -
Mineralogy at DSDP Sites 68-502 and 68-503
Eighty-four sediment samples from four holes at Site 502 and 54 samples from three holes at Site 503 were analyzed for mineral content by semiquantitative X-ray diffraction... -
Geochemistry at DSDP Holes 68-501 and 70-504B
To present one example of the variations among different laboratories in a different way, the FeO and MgO values obtained on the three standard samples are plotted in Figure 1... -
Geochemistry and minerals at DSDP Legs 68-70 Holes
The compositions of natural glasses and phenocrysts in basalts from Deep Sea Drilling Project Sites 501, 504, and 505, near the Costa Rica Rift, constitute evidence for the... -
Sample descriptions, d-spacing and geochemistry at DSDP Holes 68-501 and 69-504B
Mössbauer analyses were conducted on a sample of saponite selected from DSDP Leg 69 basalt core. The sample was initially placed within a nitrogen-purged container on-board... -
Secondary minerals and geochemistry at DSDP Legs 68 and 69
Basalt samples recovered during DSDP Legs 68, 69, and 70 from a 550-meter-thick section in two holes near the Costa Rica Rift (Holes 501 and 504B) were found to contain the... -
Geochemistry of minerals at DSDP Holes 68-501 and 69-504B
The interaction of seawater with basalts in DSDP Hole 501 and the upper part of Hole 504B (Costa Rica Rift) produced oxidative alteration and a zonation of clay minerals along...
