A trapped Philippine Sea plate origin for MORB from the inner slope of the Izu^Bonin trench
Basement outcrops sampled by submersible and dredge from the inner slope of the Izu^Bonin trench at 32‡N and 6200^6700 m water depth have a distinct mid-ocean ridge basalt (MORB) chemistry unlike any
Formation of arcs and backarc basins inferred from the tectonic evolution of Southeast Asia since the Late Cretaceous
Abstract Results of the geological and geophysical surveys in the Daito ridges and basin in the northern West Philippine Basin suggest that the Daito Ridge was an arc facing toward the south from the
Widespread submarine tephras around Japan — Petrographic and chemical properties
Abstract In deep-sea sediments around the Japanese Islands, tephra layers are frequently recognized, and some tephras can be identified by petrographic and chemical features and correlated to source
Chemistry of hydrothermal fluids at the TAG Active Mound, MAR 26°N, in 1998
Black smoker and clear fluids were sampled at the TAG active mound (26°08′N, 44°50′W) in August 1998. The major ion chemistry of the black smoker fluid appears to be stable over 12 years, indicating
Morphology and tectonics of the Yap Trench
We conducted swath bathymetry and gravity surveys the whole-length of the Yap Trench, lying on the southeastern boundary of the Philippine Sea Plate. These surveys provided a detailed morphology and
Morphology and origin of the Challenger Deep in the Southern Mariana Trench
[1] A high resolution bathymetry survey reveals the detailed morphology of the Southern Mariana Trench. Distinct right stepping, N80°E trending en echelon deeps were found on the trench bottom within
Peridotites and volcanics from the Yap arc system: implications for tectonics of the southern Philippine Sea Plate
Satellite altimetry reveals a continuous, N20°E-trending bathymetric feature, extending from the Yap Trench through the North Yap Escarpment (NYE) to the Parece Vela Rift, suggesting a genetic
Late amagmatic extension along the central and eastern segments of the West Philippine Basin fossil spreading axis
The spreading processes within the West Philippine Basin (WPB) remain partly unknown. This study presents an analysis of the tectono-magmatic processes that happened along its spreading axis during
Peridotites and gabbros from the Parece Vela backarc basin: Unique tectonic window in an extinct backarc spreading ridge
[1] Peridotite samples from a backarc basin setting will help better understand global mid-oceanic ridge processes. Here we report detailed petrological data of serpentinized peridotite and gabbro
Submersible study of an oceanic megamullion in the central North Atlantic
Recently discovered megamullions on the seafloor have been interpreted to be the exhumed footwalls of long-lived detachment faults operating near the ends of spreading segments in slow spreading
