T21A:
Planetary Thermal History and the Transition of Stagnant Lid to Plate Tectonics I

Submit an Abstract to this Session

Session ID#: 6843

Session Description:
We propose a session to bring together scientists from different disciplines to address all aspects of the evolution of planets from stagnant lid to plate tectonics, including the question of why most planets do not evolve into a plate tectonic stage and why Earth is unique in our solar system.  This is a subject of widespread interest to geoscientists as well as planetary scientists and microbiologists, and will provide and opportunity for investigators from different specialties to discuss and exchange data, models and constraints on planetary evolution.  It includes, but is not limited to, the fields of geochemistry and geochronology, thermal history of planetary interiors, and planetary geodynamic models.
