we would like to draw your attention to our multidisciplinary EGU session **[ Early Earth: Dynamics, Geology, Chemistry and Life in the Archean Earth (](https://meetingorganizer.copernicus.org/EGU2019/session/32194)**[**GD1.2/AS4.61/BG5.4/CL1.01/GMPV1.6/TS1.6)**](https://meetingorganizer.copernicus.org/EGU2019/session/32194) and hope to see you at the EGU General Assembly (7.-12. April 2019). Please note that the **deadline for abstract submission** is ** 10. January 2019** and **early-registration** is ** 28. February 2019**. We look forward to seeing you in Vienna. Kind regards, Ria Fischer Peter A. Cawood Nicholas Gardiner Antoine Rozel Jeroen van Hunen **Session GD1.2/AS4.61/BG5.4/CL1.01/GMPV1.6/TS1.6** ** "Early Earth: Dynamics, Geology, Chemistry and Life in the Archean Earth"** Processes responsible for formation and development of the early Earth (> 2500Ma) are not well understood and strongly debated, reflecting in part the poorly preserved, altered, and incomplete nature of the geological record from this time. In this session we encourage the presentation of new approaches and models for the development of Earth's early crust and mantle and their methods of interaction. We encourage contributions from the study of the preserved rock archive as well as geodynamic models of crustal and mantle dynamics so as to better understand the genesis and evolution of continental crust and the stabilization of cratons. We invite abstracts from a large range of disciplines including geodynamics, geology, geochemistry, and petrology but also studies of early atmosphere, biosphere and early life relevant to this period of Earth history.
