U24A:
FRONTIERS IN GEOSYSTEMS: Deep Earth-Surface Interactions

Note: Abstract submissions to Union sessions are by invitation only.


Session ID#: 7500

Session Description:
Recent years have seen progress in our understanding of the quantitative links between long-term Earth evolution as accommodated in the deep Earth and the evolution of the Earth’s surface systems including the ocean, atmosphere, and biosphere. This special collection consists of cutting-edge, provocative perspectives on a range of issues that have recently been tackled in this field. Those include the interactions between glacial cycles, volcanism, and climate; the link between long-term plate tectonic evolution, mantle structure, and eruption of large igneous provinces; the role of the mantle in controlling the geodynamo; feedbacks between weathering of continental and oceanic crust, tectonics, orogeny and the climate system; long term sea level variations, mantle convection, and climate; the interactions between the interior and the biosphere for the progressive rise of oxygen; and links between mantle convection and mass extinctions.
