Tectonics of Sedimentary Basin Shaofeng Liu Professor in School of Geosciences Resources • Tectonics of Sedimentary Basin (Basin Tectonics in short) is a systematic science about structure and tectonics of sedimentary basins, basin classification, mechanisms of basin formation, basin subsidence and deposition, and basin geodynamic settings. Tectonics of Sedimentary Basin • Introduction-Basins and their plate tectonic environment • Basin due to Flexure • Basin due to Extension • Strike-slip Basins • Basin Subsidence Analysis • Fundamental ideas, methods and examples in study of basin/mountain relationships References • Basin Analysis-Principles and Applications, By Philip A. Allen and John R. Allen, Blackwell Publishing, 2006 • Tectonics of Sedimentary Basins, By Cathy J. Busby and Raymond V. Ingersoll, Blackwell Scinence, Inc., 1995 Chapter 1: Introduction • Basins and their plate tectonic environment • Basin analysis - Study of sedimentary rocks to determine: – Subsidence history – Stratigraphic architecture – Paleogeographic evolution • Tools: – Geology (outcrops, wireline logs, core) – Geophysics (seismic, gravity, aeromag) – Computers (modeling, data analysis) • Basins – Definition (What is a basin?) – examples • MAKEUP of the EARTH – Compositional division – Rheological division • Plate Tectonics • Classification schemes of sedimentary basins • BASIN FORMING MECHANISMS Basins • Definition Areas of the earth where there is a net sedimentation, or in the fossil (ancient) record of such areas Zones of pronounced subsidence where sediment can accumulate. The larger the thickness of sediments and longer the accumulation has taken
