1. Sedimentary Basins

2. Sedimentary basins – definition
Large areas of positive accommodation in which
sediments can accumulate to considerable
thickness and be preserved for long geological
time periods.

3. Basin classification – plate tectonics
Type of crust on which the basin rests
The position of the basin relative to plate margins
Where the basin lies close to a plate margin, the type of plate interaction occurring during sedimentation

4. Types of plate margins:
Convergent (subduction)
Divergent (rifts, mid-oceanic ridges)
Transform (offset mid-oceanic ridges)

5. Basin classification Intraplate basins (pre-rift)
Divergent-margin basins (syn-rift)
Intraplate basins (post-rift)
Convergent-margin basins
Collision and post-collision basins
Strike-slip basins

16. Economic potential of sedimentary basins
Basin physiography
Sediment supply
Depositional environments
Architecture of depositional systems
Subsidence rates
Burial depths and burial history
Geothermal gradients
