Data derive from coulometer, CHNS analyzer, and pyrolysis oven (rock eval) -
Mineralogy and geochemistry of ODP Hole 176-735B minerals
We present a synthesis of some 20,504 mineral analyses of ~500 Hole 735B gabbros, including 10,236 new analyses conducted for this paper. These are used to construct a mineral... -
Geochemistry of ODP Hole 176-735B igneous and hydrothermal veins
During Legs 118 and 176, Ocean Drilling Program Hole 735B, located on Atlantis Bank on the Southwest Indian Ridge, was drilled to a total depth of 1508 meters below seafloor... -
Whole-rock and mineral geochemistry of ODP Hole 176-735B gabbros
We report mineral chemistry, whole-rock major element compositions, and trace element analyses on Hole 735B samples drilled and selected during Leg 176. We discuss these data,... -
Mineralogy and geochemistry of sulfide minerals and bulk rocks from ODP Hole ...
Ocean Drilling Program (ODP) Leg 176 built upon the work of ODP Leg 118 wherein the 500-m section that was sampled represented the most complete recovery of an intact portion of... -
Physical properties, velocity and attenuation characteristics, and mineralogy...
Laboratory compressional wave (Vp) and shear wave (Vs) velocities were measured as a function of confining pressure for the gabbros from Hole 735B and compared to results from... -
Geochemical composition and crystallization temperatures of ODP Hole 176-735B...
The transition from magmatic crystallization to high-temperature metamorphism in deep magma chambers (or lenses) beneath spreading ridges has not been fully described.... -
Compressional and shear wave velocities and attenuation of minicores from ODP...
Hole 735B provides a unique opportunity to compare the in situ properties of a thick sequence of oceanic gabbros with the properties of oceanic Layer 3 observed seismically... -
Isotopic ratios and geochemical composition of ODP Hole 176-735B minerals
The mineralogy and stable (O and C) and Sr isotopic compositions of low-temperature alteration phases were determined in Hole 735B gabbroic rocks in order to understand the... -
Sulphur geochemistry of whole-rock samples from ODP Hole 176-735B
Sulfide petrography plus whole rock contents and isotope ratios of sulfur were measured in a 1.5 km section of oceanic gabbros in order to understand the geochemistry of sulfur... -
Trace element geochemistry of zircons frim in situ ocean lithoshere
We characterize the textural and geochemical features of ocean crustal zircon recovered from plagiogranite, evolved gabbro, and metamorphosed ultramafic host-rocks collected... -
High-pressure experiments on a natural olivine gabbro from ODP Hole 176-735B
We have conducted high-pressure experiments on a natural oceanic gabbro composition (Gb108). Our aim was to test recent proposals that Sr-enrichment in rare primitive melt... -
Age determination of the lower oceanic crust at ODP Hole 176-735B
The cooling history and therefore thermal structure of oceanic lithosphere in slow-spreading environments is, to date, poorly constrained. Application of thermochronometric... -
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... -
Mineral, chemical and isotopic compositions of fresh and altered gabbros from...
Chemical exchange between oceanic lithosphere and seawater is important in setting the chemical composition of the oceans. In the past, budgets for chemical flux in the flanks... -
Mineral and oxygen isotopic compositions in a profile through the altered low...
ODP Hole 735B located on the Southwest Indian Ridge at 57°E is an in situ sampled long, continuous section of lower oceanic crust. Oxygen isotope compositions of constituent... -
