Cratons preserve some of Earth’s oldest continental crust and provide fundamental insights into the formation, stabilization, and dynamics of the early continents. Their emergence established long-lived, stable environments that may have influenced the development and persistence of early life. While many cratons survived since Archean, advances in seismic imaging, integrated with geochemical and geological observations suggests that some of them are modified or even destroyed in the recent past. While the mechanisms of destruction and modification remain debated, their destabilisation of the cratonic lithosphere may have disrupted deep lithospheric reservoirs, facilitating the release of volatiles into the atmosphere and establishing an important link between Earth’s deep interior, lithosphere, and atmosphere. This connection further emphasizes the economical significance of cratons, as the primary repository of diamonds and critical minerals essential for modern technologies, making their study central to the energy transition. For this session, we invite multidisciplinary contributions including but not limited to geodynamics, geochemistry, geology, seismology, and biogeodynamics. The focus is on investigating craton dynamics and its critical role in shaping Earth’s processes, from early planetary development to modern geological history.
