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 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... -
Major- and trace-elements at DSDP Legs 68-70 Holes
The basalts recovered from the Costa Rica Rift by drilling at Deep Sea Drilling Project Sites 501, 504, and 505 during Legs 68, 69 and 70 of the Glomar Challenger are the most... -
Chemiscal composition of basalts from DSDP Legs 69 and 70 Holes
Chemical compositions and 1-atm. phase relations were determined for basalts drilled from Holes 501, 504A, 504B, 505, and 505B on Legs 68, 69, and 70 of the Deep Sea Drilling... -
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... -
Composition of sediment pore water and isotopes in carbonate and benthic fora...
Two sites on the southern flank of the Costa Rica Rift were drilled on DSDP Legs 68 and 69, one on crust 3.9 m.y. old and the other on crust 5.9 m.y. old. The basement of the... -
