The alteration of upper oceanic crust entails growth of hydrous minerals and loss of
macroporosity, with associated large‐scale fluxes of H2O, CO2, Cl−, and K2O between …

This chapter reviews the boron isotopic composition of the ocean floor, including pristine
igneous oceanic crust such as mid-ocean ridge basalts and ocean island basalts and their …

Subducted crust refertilizes the subarc mantle wedge as well as the deep convecting mantle.
In the subarc region, mass transfer occurs mainly through fluids, melts, or supercritical …

We present a comprehensive major and trace element dataset establishing ODP Site 801 as
a geochemical reference for altered oceanic crust. The composition of old crustal sequences …

We present a new assessment of the pre-anthropogenic U budget for the Holocene ocean.
We find that the gross input of U to the ocean lies in the range 53±17 Mmol/year, where the …

Eclogites from the Earth's mantle found in kimberlites provide important information on
craton formation and ancient geodynamic processes because such eclogites are mostly …

The infiltration of fluids into continental lithospheric mantle is a key mechanism for
controlling abrupt changes in the chemical and physical properties of the lithospheric root …

Microbial processes within the ocean crust are of potential importance in controlling rates of
chemical reactions and thereby affecting chemical exchange between the oceans and …

More than half a gigaton of CO2 is subducted into Earth's interior each year. At least 40% of
this CO2 is returned to the atmosphere by arc volcanism,,. Processes that are known to …

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 …
