The Sequence Stratigraphy of Mixed Carbonate-Siliciclastic Depositional Systems in the Northern South China Sea, #50762 (2012)

• The paleo-topography gradients of the sequence boundaries such as SB18, SB17.5, SB17 and SB16.5 are 4.7, 0.38, 0.17 and 0.13 degrees, respectively; • The siliciclastic sediments within the sequences such as NSQ2 (21 to 18 Ma), NSQ3 (18 to 17.5 Ma), NSQ4 (17.5 to 17.1 Ma) and NSQ5 (17.1 to 16.5 Ma) were deposited in a relatively paleo-topographically low area; in contrast, the carbonate deposition occurred in high paleo-topographic areas; • In four sequences of NSQ2 (21 to 18Ma), NSQ3 (18 to 17.5Ma), NSQ4 (17.5 to 17.1 Ma) and NSQ5 (17.1 to 16.5 Ma), the carbonate sediments are overlain by the siliciclastic sediments in paleo-topographically lower area, while the carbonate is overlain by the sequence boundaries in the paleo-topographically higher area of the Dongsha uplifted area.
