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... -
Magnetic properties of Cenozoic MORB and Cretaceous MORB from DSDP and ODP holes
The fact that the natural remanent magnetization (NRM) intensity of mid-oceanic-ridge basalt (MORB) samples shows systematic variations as a function of age has long been... -
Rock magnetism and paleomagnetism of basalts at DSDP Leg 65 Holes
We investigated the magnetic and paleomagnetic properties of 77 basalt samples from Holes 482, 482C, 482D, 483, 483B, 485, and 485A in order to study the structure and... -
Physical properties and minerals of Leg 65 Holes basalts
Velocities and densities of submarine basalts obtained during Leg 65 are distinguished by their relatively high values (about 6.3 km/s and 2.9 g/cm/**3, respectively). This is... -
Atterberg limits of sediments from DSDP Leg 65 Holes
Atterberg limits have been determined for 32 unconsolidated sediment samples, ranging in composition from silty clay to sandy silt and recovered from four sites drilled at the... -
Oxygen and hydrogen isotopes at DSDP Leg 65 Holes
In order to provide information on the degree of alteration of the very young basaltic basement drilled on Leg 65 in the mouth of the Gulf of California, we have measured the... -
Geochemistry at DSDP Legs 64 and 65 Holes
Evidence for submarine hydrothermal activity along oceanic spreading centers has been accumulated from a large and diverse body of geochemical and geophysical data (e.g.,... -
Mineral chemistry of basalts from DSDP Holes 65-483 and 65-483B
During DSDP Leg 65, a series of holes was drilled into the oceanic basement across the mouth of the Gulf of California to study the composition of the crust and the nature of... -
Geochemistry and minerals at DSDP Leg 65 Holes
Petrologic studies of mid-ocean ridge basalt (MORB) (e.g., Melson et al., 1975; Flower, et al., 1977; Byerly and Wright, 1978; Melson, 1979; Byerly and Sinton, 1980; Thompson,... -
Geochemistry of selected minerals at DSDP Leg 65 Holes
The majority of the basalts drilled on Leg 65 in the Gulf of California are aphyric to sparsely phyric massive flows ranging in average thickness between 5 meters in the upper... -
Ash layers, hyaloclastite, and alteration of basaltic glass at DSDP Leg 65 Holes
Three types of tephra deposits were recovered on Leg 65 of the Deep Sea Drilling Project (DSDP) from three drill sites at the mouth of the Gulf of California: (1) a series of... -
Grain-size distribution of sediments from DSDP Leg 65 Holes
The grain-size distribution of 223 unconsolidated sediment samples from four DSDP sites at the mouth of the Gulf of California was determined using sieve and pipette techniques.... -
Mineralogy and inorganic geochemistry of sediments at DSDP Leg 65 Holes
During Leg 65, 15 holes were drilled at four sites located on young crust in the mouth of the Gulf of California. Quaternary to upper Pliocene hemipelagic sediments above and... -
Metamorphic processes in sediments at DSDP Leg 65 Holes
Sites 482, 483, and 485 were drilled during Leg 65 on young oceanic crust south of the Tamayo Transform Fault. The Leg 65 drilling program was part of a multinational effort to... -
Composition of post-Jurassic deposits from the Northwest Pacific and the Gala...
The monogragh contains results of mineralogicai and geochemical studies of Mesozoic and Cenozoic deposits from the Pacific Ocean collected during Deep Sea Drilling Project.... -
Chemical and mineral compositions of basalts from the Pacific Ocean, DSDP data
Mineral and chemical alterations of basalts were studied in the upper part of the ocean crust using data of deep-sea drilling from D/S Glomar Challenger in the main structures... -
Mineral and chemical compositions of clay sediments from the Pacific Ocean, D...
Mineral and chemical compositions, as well as conditions of formation of clay sediments in major structural elements of the Pacific Ocean floor with different ages are under... -
Petrographic data for samples from DSDP Holes 63-471 and 65-485
Detrital modes of middle Miocene sandstone recovered at Deep Sea Drilling Project Site 471 on the Magdalena Fan support the hypothesis that the fan has been displaced northward... -
Chemical and mineral compositions of basalts and volcanic glasses from DSDP S...
Major and rare earth element (REE) data for basalts from Holes 483, 483B, and 485A of DSDP Leg 65, East Pacific Rise, mouth of the Gulf of California, support a simple...
