Geodynamic and plate kinematic context of South China Sea subduction during Okinawa trough opening and Taiwan orogeny

Authigenic Carbonate Precipitation at Yam Seep Controlled by Continuous Fracturing and Uplifting of Four‐Way Closure Ridge Offshore SW Taiwan

“…The South China Sea lithosphere as part of the eastern Eurasian plate subducts eastward beneath the Philippine Sea Plate along the Manila trench (Sibuet et al., 2021) (Figure 1a). The Northern Manila Trench overlying the Luzon arc and the Ryuku arc juncture as well as the mountain belt and accretionary prism of Taiwan formed during the collision of the Philippine Sea Plate moving northwestward at a rate of 8 cm/yr (Ustaszewski et al., 2012).…”

The Early Miocene Provenance Shift of ODP Site 1177 and Implications for the Tectonic Evolution of the Shikoku Basin, Philippine Sea Plate

“…The Philippine Sea Plate is uniquely located among the Eurasian, Pacific, and Indo-Australian plates, and is of great importance to fundamental plate tectonic theory and global tectonic evolution (Hall, 2002;Reagan et al, 2010;Wu et al, 2016;Maunder et al, 2020;Sibuet et al, 2021). The Philippine Sea Plate is not only a natural laboratory for the study of plate tectonics on aspects of initial subduction, arc rifting, and back-arc spreading (Reagan et al, 2010;Arculus et al, 2015;Maunder et al, 2020;Chen et al, 2021;Li et al, 2021) but is also significant for the tectonic reconstruction of the West Pacific and East Asia (Hall, 2002;Zahirovic et al, 2014;Lallemand, 2016;Wu et al, 2016;Ma et al, 2019;Queaño et al, 2020;Liu et al, 2021;Sibuet et al, 2021).…”

“…Thus, the study of Site 1177 provenance can shed light on the Miocene tectonic evolution of the Shikoku Basin, even the Philippine Sea Plate. Previous studies have constructed the tectonic evolutionary models of the Philippine Sea Plate based on evidences from paleomagnetism (Louden, 1977;Kinoshita, 1980;Keating, 1981;Keating and Herrero, 1981;Bleil, 1982;Haston and Fuller, 1991;Haston et al, 1992;Koyama et al, 1992;Hall et al, 1995;Queano et al, 2007;Yamazaki et al, 2010Yamazaki et al, , 2021Richter and Ali, 2015;Liu et al, 2021), submarine magnetic anomaly (Okino et al, 1999;Sdrolias et al, 2004), seismic tomography (Zahirovic et al, 2014;Wu et al, 2016;Ma et al, 2019;Sibuet et al, 2021) and sedimentary provenance (Clift et al, 2013;Saitoh et al, 2015), etc. Researchers agreed on the first-order evolution that the Philippine Sea Plate moved ~20 °northward from the equator to the present position and simultaneously rotated ~90 °clockwise since the Eocene (Hall, 2002;Yamazaki et al, 2010;Zahirovic et al, 2014;Wu et al, 2016;Ma et al, 2019;Liu et al, 2021).…”
