Principle of the “tectono-sedimentary analysis” and its application in sedimentary basins

The tectono-sedimentary analysis uses 3D seismic data to study dynamic controls of synsedimentary tectonics on sedimentation evolution.It aims to construct the relationship between tectonics and sedimentation.Compared with tectonostratigraphy,the tectono-sedimentary analysis emphasizes application of 3D seismic technique,and tectonic dynamic controls on both sedimentary processes and sedimentary filling.This study provides new thoughts and developments of the tectono-sedimentary analysis in the following aspects: 1) tectonic analysis;2) tectonic controls on sedimentary processes;3) response relationship between tectonics and sedimentary filling.The analysis of growth strata,grain size and 3D seismic technique are the three key methods used for the tectono-sedimentary analysis,which will have further application and deepening in the complex research of tectonics processes and sedimentary products in future.
