V51C:
Interdisciplinary Perspectives on Continental Crust Evolution II Posters


Session ID#: 11040

Session Description:
There are still many outstanding questions regarding the modus operandi of continental crust formation and destruction, its volume, composition, thickness, and its interaction with the mantle and the atmosphere through time; especially during the early stages of Earth's evolution. New perspectives are rising from the increased understanding of the geochemical record preserved in igneous and sedimentary rocks, minerals and their inclusions, the improvement of analytical techniques, and the development of both analogue and numerical modeling of crust-mantle interaction through time. This session welcomes contributions that address the origin and evolution of the crust and/or the lithosphere, using one or a combination of these different approaches. Contributions that present new approaches and/or new (interdisciplinary) analytical techniques will be particularly welcome.
