Unravelling the history of cratonic sedimentary basins
Cratonic basins are enigmatic large depressions situated on thick and stable continental shield, or ‘craton’. Their subsidence history in many cases continues through cycles of super-continent dispersal and assembly, and so present a unique archive of planetary evolution. Different mechanisms for the formation of cratonic basins have been put forward, such as cooling of the continental lithosphere, mantle flow, and long-wavelength deformation, but so far no generic formation mechanism is universally agreed upon. The long and often complex history of subsidence and episodic uplift of these basins still remains difficult to model in detail.
In this symposium we aim to discuss cross-disciplinary analyses of cratonic sedimentary basins to highlight the state-of-the-art in basin research and define future avenues of research. We invite contributions over a broad range, such as stratigraphic analyses, kinematic and dynamic modelling, potential field analyses, and observations from structural geology and seismology. We envisage to compare insights of cratonic basins worldwide, for example, in North America (the Michigan and Illinois Basins), South America (the Amazonian, Parnaiba and Parana Basins), Eurasia (the Paris, Moscow and West Siberian Basins), and in particular in Africa, e.g. the Congo, Chad, Taoudeni, and Kalahari Basins.
