Geodynamics Dynamics: Relationship between force and motion (Also force in equilibrium) Geodynamics: Dynamics of Earth (Mantle has a hegemony here) Why? Crust : Geology Core: Magneto-Hydrodynamics (MHD) Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 11 01-08-2020
Into the modeling world A scientific model is a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes. All models are beautiful! Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 12 01-08-2020
Why Geodynamicists model? • Time scale of natural process: Real time experiment is impossible • Number of variables/ unknown in natural system • Non-intuitive nature of physical properties • Non-linear nature of governing equations Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 13 01-08-2020
My Present Work Why cratons are still here? One of the grand challenges in Geodynamics (Olson et al. 2010) (Poupinet and Shiparo, 2008, Lithos) Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 14 01-08-2020
How do continents destroy? Hypothesis for craton survival: Cratons are lighter in density What about convective erosion? (Karato 2010) Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 15 01-08-2020
Convective erosion Do the cratons need to be strong? How strong? Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 16 01-08-2020
