Experimental evidence for the dynamics of the formation of the Yinggehai basin, NW South China Sea

Zircon U-Pb geochronology and heavy mineral composition constraints on the provenance of the middle Miocene deep-water reservoir sedimentary rocks in the Yinggehai-Song Hong Basin, South China Sea

“…The basin formed in Cenozoic time due to the southeastward strike-slip deformation and clockwise rotation of the Indochina Block as a result of the collision and indentation of India into Asia and seafloor spreading of the South China Sea (Fig. 1) Tapponnier, 1975, 1978;Tapponnier et al, 1986;Rangin et al, 1995;Guo et al, 2001;Morley, 2002;Sun et al, 2003). The Y-SH Basin is bordered on the north and east by the Beibuwan and Qiongdongnan basins, respectively (Fig.…”

“…The pressure coefficient and geothermal gradient can reach 2.0e2.3 and 4.25e4.56 C/100 m, respectively (Zhang et al, 1996;Huang et al, 2002Huang et al, , 2003. The depocenters are mainly controlled by NW-and roughly N-Strending faults (Sun et al, 2003), which show a migration to the southeastern basin between 21 and 16 Ma, which led to basin inversion and formation of an angular unconformity (Rangin et al, 1995;Clift and Sun, 2006). During 16e5.5 Ma, depocenters gradually migrated back to the northwest, and paused in the northwestern basin ).…”

Late Miocene provenance change on the eastern margin of the Yinggehai-Song Hong Basin, South China Sea: Evidence from U–Pb dating and Hf isotope analyses of detrital zircons

“…The basin was developed on the northern margin of the South China Sea continental shelf, and the formation was generally considered to be related to the southeastward strike-slip deformation and clockwise rotation of the Indochina Block as a result of the collision and indentation of India into Asia (Fig. 1A) (Molnar and Tapponnier, 1975;Tapponnier et al, 1986;Guo et al, 2001;Sun et al, 2003;Yan et al, 2011). The basin is bordered on the north and east by the Beibuwan and Qiongdongnan basins, respectively (Fig.…”

Provenance of Upper Miocene to Quaternary sediments in the Yinggehai-Song Hong Basin, South China Sea: Evidence from detrital zircon U–Pb ages

“…1B). The basin developed in response to the southeastward strike-slip faults and clockwise rotation of the Indochina Block as a result of India-Asia collision (Molnar and Tapponnier, 1975;Tapponnier et al, 1986;Guo et al, 2001;Sun et al, 2003;Yan et al, 2011a) (Fig. 1A).…”
