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... -
Mean grain size and structure of ODP Hole 140-504B samples
Microstructural investigations of ocean crust samples provide a complementary approach to both marine surveys and laboratory experiments. The recovery of relatively undeformed... -
Chemistry of phyllosilicates of ODP Hole 140-504B
Replacement minerals in olivine record the evolution of hydrothermal alteration between 1600 and 2000 mbsf in the sheeted dike complex in Hole 504B.1. Talc (+ magnetite) rim on... -
Platinum group elements and geochemistry of altered oceanic crust of ODP Hole...
Primary chemical heterogeneity in the sheeted dike complex in Deep Sea Drilling Project Hole 504B makes these rocks unsuitable for conventional mass balance calculations in... -
Geochemistry of sheeted dike complex minerals of ODP Hole 140-504B
Diabases were recovered during Legs 137 and 140 at Hole 504B from depths between 1621.5 and 2000.4 meters below seafloor in the lower sheeted dike complex. The samples contain... -
Geochemistry of clinopyroxene megacrysts, xenocrysts, and phenocrysts in diab...
We report the major, rare earth, and other trace element compositions of clinopyroxenes from two Leg 140, Hole 504B diabase dikes. These pyroxenes reflect a complex history of... -
Petrology and geochemistry of altered ocenaic crust of ODP Hole 140-504B
Altered basalt dikes from Hole 504B were partially melted at 1150°C and 1180°C to determine the composition of the first melts as oceanic Layer 2C is assimilated by a magma... -
Geochemical compositions of minerals from chilled dike margins of ODP Hole 14...
Mineral and whole-rock geochemical data are presented for chilled dike margins from the lower sheeted dike complex of Deep Sea Drilling Project/Ocean Drilling Program (DSDP/ODP)... -

Ocean Drilling Program (ODP) Hole 504B near the Costa Rica Rift is the deepest hole drilled in the ocean crust, penetrating a volcanic section, a transition zone and a sheeted... -
Strontium chemistry of anhydrite from DSDP/ODP Hole 504B
A unique record of the chemical evolution of seawater during hydrothermal recharge into oceanic crust is preserved by anhydrite from the volcanic sequences and sheeted dike... -
Geochemistry, and Nd- and Pb-isotopic composition of basalts from the upper o...
The DSDP/ODP Hole 504B, drilled in the 5.9 Ma southern flank of the Costa Rica Rift, represents the deepest section through modern ocean floor basaltic basement. The hole... -
