| Scope | The latest results of Earth's evolution and geological processes through 4.6 billion year s from Hadean to Modern, based on various approaches including fieldworks, chemical analyses, experiments and computer simulation, will be presented. In this session, we ai m to discuss and understand causal relationships and interplay among the evolution of Earth's deep interior, changes in the surface environments, and development and evolut ion of life. Wide-ranging topics are accepted. | |
