Structural and Kinematic Evolutions of the Okinawa Trough Backarc Basin,n Okinawa Trough to 30 km in the northern Okinawa Trough. The Okinawa Trough is still in a rifting stage. In the southern Okinawa Trough, magnetic anomalies are linked either to limited arc volcanic intrusions located on the northern side of the Ryukyu arc, to the axis of the main depressions where

Opening Tectonics of the Japan Sea, Japan Sea was initiated by the extension and thinning of the proto-Japan island arc, which was situated on the margin of the Eurasian continent at ca. 30 Ma. During the extension process a large strike-slip fault was generated at the eastern margin of the proto-Japan Sea. The strike-slip movement c

Kuril (South Okhotsk) Backarc Basin,hich is 7–8 km deep, and it contains 4 to 5+ km of technically undisturbed sedimentary fill. The oldest sedimentary rocks sampled from the basin margin are Miocene/Oligocene. Although no seafloor spreading magnetic lineations exist, we conclude that the basin has formed by backarc extension and spre

Hydrothermal Activity Related to Arc-Backarc Magmatism in the Western Pacific,luid chemistry. These sites constitute about 20% of the known seafloor hydrothermal sites, which are dominated by those occurring at mid-ocean ridges (MORs). High-temperature hydrothermal activities in the western Pacific exclusively occur in association with submarine volcanism found either on back

Tectonic and Magmatic Controls on Backarc Basin Sedimentation,axis. These models are adequate in the case of backarc rifting, but a more dynamic model is needed in the case of forearc rifting. We present a revised model for backarc basin sedimentation that reflects progressive shifts in volcanism and associated depocenters through the history of a backarc basi

Rates of extension in the currently active TVZ are about 7 mm/yr in the north and 18 mm/yr in the south, derived from shear strain rates varying between 0.18 and 0.5 × 10./yr shear. Subsidence rates are 1–2 mm/yr. Focal mechanisms from recent small earthqu

Contrary to previous models, the entire Havre Trough is now interpreted to be undergoing backarc rifting prior to true spreading, with the attendant tectonic fabric dextrally oblique to the bounding Colville and Kerm

The second stage of opening (about 5.5-5 Ma) was promoted by a southward-propagating rift system that formed new crust by seafloor spreading. A second propagator (ab
