Heavy Mineral Compositions of Sediments in the Southern Okinawa Trough and Their Provenance-Tracing Implication

open access: yes, 2021
Heavy mineral assemblages have been widely used to effectively trace sediment sources. Heavy mineral assemblages are rarely used in research to trace sediment sources in the southern Okinawa Trough compared with geochemical proxies.

Heat flow in the southwestern Okinawa Trough

open access: yesEarth and Planetary Science Letters, 1981
Abstract Lying to the southeast of the East China Sea continental shelf, the Okinawa Trough is believed to have been formed by crustal spreading behind the Ryukyu island arc. It has the highest mean heat flow among the Pacific marginal basins. The mean of 18 reliable measurements is3.34±2.75HFU.

Geomagnetic anomalies in the middle Okinawa Trough.

open access: yesJournal of Geography (Chigaku Zasshi), 1985
Geomagnetic survey by means of the proton magnetometer and the three component magnetometer was carried out by the RN 83 Cruise of the Nagasaki Maru to reveal Pleistocene igneous activities along the axial median valley (central rift) of the middle Okinawa Trough in 1983.Preliminary results are as follows:(1) Magnetic anomaly lineations were clearly ...

Sea surface temperature oscillations in southern Okinawa Trough during last 2700 years from ODP Hole 195-1202B

open access: yes, 2012
Most of the temperature reconstructions for the past two millennia are based on proxy data from various sites on land. Here we present a bidecadal resolution record of sea surface temperature (SST) in Southern Okinawa Trough for the past ca.

Source area of the 1858 earthquake swarm in the central Ryukyu Islands revealed by the observations of Father Louis Furet

open access: yesEarth, Planets and Space, 2017
We estimated the location and magnitude of earthquakes constituting the 1858 earthquake swarm in the central Ryukyu Islands using the felt earthquakes recorded by Father Louis Furet who lived in Naha, Okinawa Island, in the middle of the nineteenth ...

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

open access: yesGeological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.
