The Geodynamics of Cratons
The Geodynamics of Cratons
Session ID#: 74916
Session Description:
Being the oldest lithosphere, cratons have experienced the consequences of complex geodynamic processes that have operated since the Archean. These thick, cold and old lithosphere provide us with a way to study the Archean earth. Moreover, their unique lithospheric properties often influence present-day lithosphere-mantle interactions. The reason behind cratonsâ long-term survival is one of the most outstanding questions in Earth Sciences and was first addressed in the mid-70s. However, a definitive explanation is still elusive. The other issues associated with the cratons, such as their origin, density and viscosity structure, thickness, chemical heterogeneity and destructive mechanisms can be probed using numerical modeling, field data, geochemical studies and seismic imaging. Recently, the discovery of mid-lithospheric discontinuity has added more complexity to the craton problem. In this session, we welcome contributions that intend to investigate the geophysical and geochemical problems related to cratons, both at the global and regional scales.
