A new box model for the global carbon-calcium-strontium cycle is developed to simulate the
evolution of Cretaceous and Cenozoic seawater and atmosphere. The model accounts for …

Over 50% of Earth is covered by oceanic crust, the uppermost portion of which is a high-
permeability layer of basaltic lavas through which seawater continuously circulates. Fluid …

In subduction zones, sediments and hydrothermally altered oceanic crust, which together
form part of the subducting slab, contribute to the chemical composition of lavas erupted at …

Convective circulation of seawater through oceanic crust at mid-ocean ridges (MOR) and on
ridge flanks has wide-ranging effects on heat transport, the chemical and isotopic …

The distributions and abundances of alteration types and carbonate minerals in sections of
upper ocean crust have been measured in order to determine the carbon budget in altered …

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 …

Low-Grade Metamorphism explores processes and transformations in rocks during the early
stages of metamorphic recrystallization. There has been little analysis and documentation of …

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 …

We present elemental and isotopic data detailing how the Mg isotope system behaves in
natural and experimentally synthesized clay minerals. We show that the bulk Mg isotopic …

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 …
