Boron isotope exchange between seawater and the oceanic crust
Arthur J. Spivack,John M. Edmond +1 more
TLDR
In this article, a large scale boron exchange between seawater and the oceanic crust has been demonstrated at both high and low temperature, and the B content of altered whole rocks correlates strongly with δ18O, and increases with degree of alteration.About:

Boron isotopic composition and concentration in modern marine carbonates
N. G. Hemming,Gilbert N. Hanson +1 more
TL;DR: In this paper, negative thermal ionization mass spectrometry was used to analyze the boron isotopic compositions of modern marine carbonates with a 2σ reproducibility of standards and samples better than 0.7%.

Geochemistry of subduction zone serpentinites: A review
TL;DR: A review of the geochemistry of serpentinites, based on the compilation of ~900 geochemical data of abyssal, mantle wedge and exhumed serpentinite after subduction, is presented in this paper.

TL;DR: In this paper, the first hydrothermal fluid samples collected along the slow-spreading Mid-Atlantic Ridge (MAR) are remarkably similar in composition and temperature to fluids collected on the East Pacific Rise (EPR), and they appear to be in equilibrium with a greenschist-facies mineral assemblage.

Temperature and pH controls over isotopic fractionation during adsorption of boron on marine clay
TL;DR: In this paper, the variation of adsorption constants and isotope fractionation with pH and temperature during the adaption of B from seawater onto marine clay has been examined.

Geochemistry of hydrothermal fluids from Axial Seamount hydrothermal emissions study vent field, Juan de Fuca Ridge: Subseafloor boiling and subsequent fluid‐rock interaction
TL;DR: In this paper, a single hydrothermal fluid undergoing phase separation while rising through the ocean crust, followed by partial segregation of the vapor and brine phases is explained by the fluid-rock interaction in the upflow zone.

The chemical evolution of the atmosphere and oceans
TL;DR: Holland et al. as mentioned in this paper reconstruct the chemical evolution of the Earth's atmosphere and oceans using data from a wide spectrum of fields to trace the history of the ocean-atmosphere system.

Chemistry of submarine hydrothermal solutions at 21 °N, East Pacific Rise
TL;DR: The major ion data are consistent with the estimates based on extrapolation of the original measurements made on the hot springs from the Galapagos Spreading Center ( Edmond et al., 1979a).

TL;DR: In this paper, samples collected by the deep submersible Alvin from four hot spring fields (T = 3 − 13°C) on the crest of the Galapagos spreading ridge show pronounced and varied compositional anomalies.

An oxygen isotope profile in a section of Cretaceous oceanic crust, Samail Ophiolite, Oman: Evidence for δ18O buffering of the oceans by deep (>5 km) seawater-hydrothermal circulation at mid-ocean ridges
Robert T. Gregory,Hugh P. Taylor +1 more
TL;DR: In this paper, isotopic analyses of 75 samples from the Samail ophiolite indicate that pervasive subsolidus hydrothermal exchange with seawater occurred throughout the upper 75% of this 8 km-thick oceanic crustal section; locally, the H_2O even penetrated down into the tectonized peridotite.
