TECTONICS OF RIFT BASINS
4 Dezembro 2024, 11:00 • Pedro Antonio Gancedo Terrinha
1. Pure shear model (McKenzie model) illustrating stretching andthinning of the lithosphere.
2. Rheological composition of the lithosphere and different mechanical behaviour of mineral phases.
3. Lithosphere strength and development of weak zones in the crust and lithospheric mantle.
4. Tectonic detachments as a consequence of zones of weakness.
5. Underplating during rifting process: examples from the Red Sea and East Africa Rift (intra-continental rifting) and the Terceira Rift (Oceanic rifting)
6. Subsidence: tectonic subsidence as a result of crustal thinning; thermal subsidence as a result of thermal controlled density variation of the lithosphere.
7. Models of lithospheric stretching and thinning: pure versus simple shear and heterogenous shear. Consequences in overall basin geometry.
