T41A:
(De)Cratonization Dynamics I


Submit an Abstract to this Session


Session ID#: 57030

Session Description:
Cratons can record a complex genetic history, both within them and at their margins, including patterns that are compatible with subduction/accretion processes and continental rifting. This complexity can be addressed through integrated tectonic studies based on geophysical imaging techniques, geochemical and isotopic studies and geodynamic modelling. We invite contributions that address the structural and compositional aspects of craton formation and craton destruction globally, as well as studies that compare cratonic lithosphere to continental regions of younger age.
