Roerdink, Richard Palin and myself
hope to see you in Vienna

*Cratons through time: Geodynamics, Geochemistry and the Evolution of a
Habitable Planet*
Cratons hold the record of the oldest crust. Their formation and evolution
into a stable continent set the conditions for early life to thrive on this
planet. Emergence of Archean cratons above the sea level formed shallow
marine environments, which potentially harboured early life, and exposed
silicate-rich rocks to surface weathering. It significantly modulated
atmospheric CO₂ levels and helped regulate climate, a fundamental process
to sustain long-term habitability.
While many cratons survived since Archean, some of them are modified or
even destroyed in the recent past. Their destruction might have disrupted
lithospheric volatile reservoirs, releasing them into the atmosphere.
Insights into these processes can improve present-day Earth system models,
particularly those exploring carbon cycling and climate stability.
Cratons are also economically significant. They are the primary repository
of diamond and also rich in critical minerals essential for modern
technologies and the energy transition, making their study increasingly
relevant today.
For this session, we invite multidisciplinary contributions including but
not limited to geodynamics, geochemistry, geology, geophysics, and
biogeodynamics. The focus is on investigating craton evolution and its
critical role in shaping Earth’s processes, from early planetary
development to modern geological history.
