2011年1月5日 · Our calculations indicate that mineralogically bound water can pass efficiently through old and fast subduction zones (e.g., in the western Pacific), whereas hot subduction zones such as Cascadia see nearly complete dehydration of the subducting slab.

2003年1月18日 · These calculations provide a new basis for evaluating the subduction factory, including (1) the presence of hydrous phases and the distribution of H 2 O within a subduction zone; (2) the densification of the subducting slab and resultant effects on measured gravity and slab shape; and (3) the variations in seismic wave speeds resulting from ther...

2004年1月1日 · Subduction zones helped nucleate and grow the continents, they fertilize and lubricate the earth's interior, they are the site of most subaerial volcanism and many major earthquakes, and they yield a large fraction of the earth's precious metals.

The subduction factory processes raw materials such as oceanic sediments and oceanic crust and manufactures magmas and continental crust as products. Aqueous fluids, which are extracted from oceanic… Subduction-zone metamorphism is considered to be a major chemical filter for both the arc magmatism and mantle compositional heterogeneity.

2011年1月5日 · We model three-dimensional, dynamic subduction and examine the time evolution of the along-strike temperature difference of the slab’s upper surface (“slab-top”) at the center relative to the...

Subduction zones, where the oceanic plates sink into the mantle, have been “factories” since plate tectonics began on Earth (Fig. 1). Oceanic materials such as pelagic and ter-rigenous sediments, altered and fresh basaltic oceanic crust, and mantle lithosphere enter the factory as …

The subduction factory processes raw materials such as oceanic sediments and oceanic crust and manufactures magmas and continental crust as products.

2005年7月1日 · The subduction factory processes raw materials such as oceanic sediments and oceanic crust and manufactures magmas and continental crust as products.

2015年10月7日 · The Subduction Factory recycles raw materials from the seafloor and underlying mantle, creates products on the upper plate in the form of melts, aqueous fluids and gases, and modulates the dynamics of plate tectonics. The relationship of magma output and composition to forcing functions such as convergence rate, plate age, and sedimentary input.

2004年1月20日 · [1] An Excel macro to calculate mineral and rock physical properties at elevated pressure and temperature is presented. The workbook includes an expandable database of physical parameters for 52 rock-forming minerals stable at high pressures and temperatures.
