Subduction dynamics at the middle America trench : new constraints from swath bathymetry, multichannel seismic data, and 10BE
… The range in 10Be enrichment in the Central American Volcanic Arc between Guatemala and Costa Rica is not controlled by variations in 10Be concentrations in subducting sediment seaward of the Middle America Trench. Sedimentary 10Be is correlated negatively with 143Nd/144Nd, illustrating that …

Subduction dynamics at the middle America trench : new constraints from swath bathymetry, multichannel seismic data, and ¹⁰Be
… The range in ¹⁰Be enrichment in the Central American Volcanic Arc between Guatemala and Costa Rica is not controlled by variations in ¹⁰Be concentrations in subducting sediment seaward of the Middle America Trench. Sedimentary ¹⁰Be is correlated negatively with ¹⁴³ND/¹⁴⁴Nd, illustrating that …

Evolution of oceanic margins : rifting in the Gulf of California and sediment diapirism and mantle hydration during subduction
… from wide-angle, active-source data from the Middle America Trench that address the hypothesis that the upper mantle is hydrated by seawater flowing along outer-rise normal faults. These measurements indicate that the upper mantle is ~1.57 to 6.89% anisotropic, and this anisotropy can be …

Offshore El Salvador: the first interpretation of a unique 2-D seismic dataset and implications for a working petroleum system in a forearc basin setting
… basins that lie between the coast of Central America and the Middle America Trench, running parallel to the Pacific coastline from central Mexico to Costa Rica. Interpretation of 3,700 kms of 2D seismic data reveal the presence of a deep depositional basin bounded on the northeast by the …
