Session ID#: 7746
Session Description:
Placing constraints on the geodynamic evolution of the Earth’s mantle, from terrestrial accretion to the present day, is critically important to a wide range of disciplines examining the deep Earth. Long-standing models for the bulk composition of the Earth have been called into question. The discovery of small isotopic difference between the Earth and the chondritic reservoir has had enormous impact in Earth Science, from introducing new ideas like collisional erosion to suggesting hidden reservoirs in the deep mantle, and has forced the community to re-evaluate Earth’s chemical composition and structure. In this session we invite contributions that further our understanding of the formation and structure of the Earth, its bulk composition, and the evolution of the crust-mantle system over 4.5 Ga. We welcome a multidisciplinary and integrative approach to the above problems and encourage contributions from the related fields of geochemistry, geodynamics, seismology and mineral physics.
