Structural characteristics of the northern Okinawa Trough and adjacent areas from regional seismic reflection data: Geologic and tectonic implications

Analysis of regional multi-channel seismic data from the northern Okinawa Trough and adjacent shelf provides some important constraints on the structural development of the area. The sedimentary strata in the northern East China Sea shelf basin, separated from the Okinawa Trough by the Taiwan–Sinzi belt, are affected by the Miocene compressional tectonism and truncated by the Late Miocene unconformity. In contrast, those in the western margin of...
