Tectonic unit divisions based on block tectonics theory in the South China Sea and its adjacent areas

Depth distribution of Moho model and tectonic patterns in South China Sea and adjacent areas

“…Liu et al used magnetic anomaly data to identify comprehensive boundaries in the northern South China Sea [ 8 ]. Yin et al divided South China Sea and adjacent area into nine stable blocks, two suture zones, two accretionary zones, one subduction-collision zone, one ramp zone, and six small oceanic marginal sea basins [ 9 ]. The existing methods for boundary recognition are mostly based on the gravity horizontal or vertical derivative.…”
