Session Description:

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.

Hope to see you in Vienna.

Best regards
