6th International Archean Symposium

Early Earth geodynamics

At present, Earth’s mantle convection, which facilitates planetary heat loss, is expressed at the surface as plate tectonics. However, how and when plate tectonics emerged and evolved, and what, if anything, came before are among the most fundamental outstanding questions in Earth science. Given the scarcity of truly ancient rocks, increasingly sophisticated modelling techniques potentially provide the best opportunity to unravel early Earth evolution. We invite contributions that aim to better understand the dynamic evolution of Earth during the Hadean and Archean using geochemical, isotopic, phase equilibrium and numerical modelling.
