Seismic velocities and elastic properties of gabbroic rocks from ODP Hole 118...
The nearly continuous recovery of 0.5 km of generally fresh, layer 3 gabbroic rocks at Hole 735B, especially near the bottom of the section, presents scientists an unusual... -
Petrography and geochemical composition of the Atlantis II Fracture Zone
SeaBeam echo sounding, seismic reflection, magnetics, and gravity profiles were run along closely spaced tracks (5 km) parallel to the Atlantis II Fracture Zone on the Southwest... -
Magnetic properties of gabbros from ODP Hole 118-735B
A total of 500.7 m of continuous, vertical, oceanic gabbroic section was recovered during Leg 118. The gabbros obtained exhibited various degrees of alteration and deformation,... -
Geochemistry of vein rocks of ODP Hole 118-735B
Rock samples from Hole 735B, Southwest Indian Ridge, were examined to determine the principal vein-related types of alteration that occurred, the nature of fluids that were... -
Chemistry of gabbroic rocks from ODP Hole 118-735B
Gabbroic rocks and their late differentiates recovered at Site 735 represent 500 m of oceanic layer 3. The original cooling of a mid-ocean ridge magma chamber, its penetration... -
Geochemistry and mineralogy of sediments from the Atlantis II Fracture Zone
Thirteen sediment samples, including calcareous ooze, sandy clay, volcanic sand, gravel, and volcanic breccia, from Ocean Drilling Program (ODP) Sites 732B, 734B, 734G and... -
Mineralogy and textures of gabbros from ODP Hole 118-735B
Abundant iron-titanium (Fe-Ti) oxide gabbro, olivine gabbro, and troctolite were drilled at Hole 735B adjacent to the Atlantis II Fracture Zone of the Southwest Indian Ridge... -
Geochemistry and isotopic composition of gabbros from ODP Hole 118-375B
Gabbros drilled from the shallow (720 m) east wall of the Atlantis II transform on the Southwest Indian Ridge (SWIR; 32°43.40', 57°16.00') provide the most complete record of... -
Mineralogy and isotopic composition of sulfur in ODP Hole 118-735B gabbros
Sulfide mineralogy, sulfur contents, and sulfur isotopic compositions were determined for samples from the 500-m gabbroic section of Ocean Drilling Program Hole 735B in the... -
Magmatic oxides and sulfides in gabbroic rocks from ODP Hole 118-735B
Extended high-iron differentiation occurred while the gabbroic rocks of Hole 735B were undergoing intense ductile and brittle deformation beneath a spreading ridge segment near... -
Chemistry of gabbroic rocks of ODP Hole 118-735B
We present results of a microprobe investigation of fresh and least-deformed and metamorphosed gabbroic rocks from Leg 118, Hole 735B, drilled on the east side of the Atlantis... -
Helium and neon isotopes in oceanic crust of ODP Hole 118-735B
In an attempt to determine the helium and neon isotopic composition of the lower oceanic crust, we report new noble gas measurements on 11 million year old gabbros from Ocean... -
Results of analyses of fluid inclusions from ODP Site 735B, Leg 118 and 176
Microthermometric and isotopic analyses of fluid inclusions in primitive olivine gabbros, oxide gabbros, and evolved granitic material recovered from Ocean Drilling Program Hole... -
Chemical and isotopic compositions of rocks and minerals from ODP Hole 118-735B
A novel strip-sampling technique has been applied to the 500-m gabbroic section drilled at site 735 during Leg 118. Twenty-two continuous strips of 1.1- to 4.5-m length were cut...
