摘要
In order to better understand the mechanism and characteristic of foreland basin evolution in the Nansha trough, the authors studied the structure, sedimentology and other characteristics of the basin based on the geophysical data of the past decades collected from South China Sea Institute and recent research progress both at home and abroad. An elastic lithospheric plate flexure model for Nansha Trough foreland basin is established. With the model, the authors reconstructed the history of deposition, subsidence, tectonic movement and deflection and deformation process in the basin, and predicted the geometry, gravity anomaly, sediment thickness of the basin in different stages.
