Significance of mud volcanism
TL;DR: The authors summarizes the main thrusts in mud volcano research as well as the various regions in which mud volcanism has been described, including the collision zones between Africa and Eurasia, where fluid flux through mud extrusion exceeds the compaction-driven pore fluid expulsion of the accretionary wedge.

The Chemical Composition of Subducting Sediments
TL;DR: In this article, the mass flux of Li subducted into different trenches correlates strongly with the Li/Y ratio in adjacent volcanic arcs, pointing to a direct control on Li enrichment in arcs by subducting sediment.
Journal ArticleDOI
The geochemistry of carbonate diagenesis: The past, present and future
TL;DR: For example, in this article, the authors present a method for interpreting carbonate diagenesis of carbonate rocks by analyzing the δ18O value of any fluid inclusions or by measuring the temperature using a method such as the clumped isotope technique.
Journal ArticleDOI
Origin of the slab component in arc lavas from across-arc variation of B and Pb isotopes
TL;DR: In this paper, across-arc variations in the concentrations and isotopic compositions of boron and lead observed in lavas from the Izu arc (Japan) have been reported, suggesting that a homogeneous slab fluid contributes to all Izu volcanoes, but that the amount of this fluid decreases continuously with increasing depth of the subducting slab.

Mechanism of burial metamorphism of argillaceous sediment: 1. Mineralogical and chemical evidence
TL;DR: In this paper, a detailed mineralogical and chemical investigation of shale cuttings from a well (Case Western Reserve University Gulf Coast 6) in Oligocene-Miocene sediment of the Gulf Coast of the United States was made by x-ray diffraction.
Journal ArticleDOI
Chemistry of Pacific pelagic sediments
TL;DR: The chemical and mineralogical composition of pelagic sediments from the East Pacific Ocean has been determined with the aim of defining the ultimate sources and the mechanisms of formation of the solid phases.

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%.

The distribution of clay minerals in the World Ocean
TL;DR: In this article, the relative amounts of chlorite, montmorillonite, kaolinite and illite in the less than 2 micron size fraction of pelagic sediments are related to the sources and transport paths of solid phases from the continents to the oceans and to injections of volcanic materials to the marine environment.

Boron isotope exchange between seawater and the oceanic crust
Arthur J. Spivack,John M. Edmond +1 more
TL;DR: 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.
