We emphasize the importance of marine silicate weathering (MSiW) reactions in anoxic
sediment as fundamental in generating alkalinity and cations needed for carbonate …

The stability of submarine gas hydrates is largely dictated by pressure and temperature, gas
composition, and pore water salinity. However, the physical properties and surface …

Processes in subduction zones such as slab and mantle‐wedge metamorphism, intraslab
earthquakes, and arc volcanism vary systematically with the age‐dependent thermal state of …

The oceanic Cocos Plate subducting beneath Costa Rica has a complex plate tectonic
history resulting in segmentation. New lines of magnetic data clearly define tectonic …

Subduction erosion is commonly associated with strong interplate coupling and a
consequent abrasion of the upper plate. Northern Chile is an often cited example of a …

Fluid distribution in convergent margins is by most accounts closely related to tectonics. This
association has been widely studied at accretionary prisms, but at half of the Earth's …

The relative rates of creation and destruction of continental crust at subduction zones are a
key factor shaping the evolution of continental crust through time. Central America, arguably …

To understand the role of subducted sediment in arc magmatism and the formation of the
continental crust, we have determined the Li isotopic composition of marine sediments …

A systematic search for methane‐rich fluid seeps at the seafloor was conducted at the
Pacific continental margin offshore southern Nicaragua and northern central Costa Rica, a …

New thermal data from 18–24 Ma lithosphere on the Cocos Plate delineate contrasting
subsurface thermal conditions in adjacent sections of crust. Heat flow through seafloor …
