4-4-4-4-4-4-4-4-4-4-4-4-4 From: geolnh <Lauren.N.Harrison@xxxxxxxxxxxxx> Dear Colleagues, We invite abstract submissions our AGU session on mantle geochemistry and mantle plume derived magmas at the 2023 AGU Fall Meeting in San Francisco, CA. The description of the session is as follows: *V006* " Chemistry and Evolution of Earthâ??s Interior as Recorded by Mantle Plumes" <https://urldefense.com/v3/__https://agu.confex.com/agu/fm23/prelim.cgi/Session/189526__;!!IKRxdwAv5BmarQ!b1haa20OxxmKLHiPC9VA0ivpkCNJXz_XdEeP0dr0P0kDiVbulvjNlAXAlITCNEXEIy_WMmRDz1WQNYC6wbp9ka3LR_wiuG8$> : â??The Earthâ??s mantle is an important chemical reservoir with a complex history. Exchanges between the mantle and other Earth reservoirs, such as the atmosphere, crust, core, and hydrosphere, have fundamentally influenced the evolution of the entire Earth system. â??Primaryâ?? mantle plumes originate from the mid to lower mantle and produce intraplate lavas that carry geochemical tracers of their deep mantle sources. The geochemistry of plume-formed rocks can help constrain Earthâ??s initial composition, the formation and preservation of ancient chemical reservoirs and continental crust, the onset of subduction and recycling, and the dynamic mixing of heterogeneities through time. This session will focus on the geochemistry of Earthâ??s mantle as recorded by mantle plume melts, with an emphasis on ocean island basalts and large igneous provinces. We welcome submissions using geochemical, geochronological, geodynamic, and isotopic tools to explore the origin, scale, extent, and preservation of mantle chemical heterogeneity over Earthâ??s entire history.â?? The abstract deadline is Wednesday, 2 August 2023 23:59 EDT/03:59 +1 GMT and the abstract submission website is here: https://urldefense.com/v3/__https://www.agu.org/agu23__;!!IKRxdwAv5BmarQ!crM6dHDm_RKNVfQYZwQE4pMkfshc8xDqfZPD6J_TxgXJox5aw1yoFFQj6naBEAuxvKIsoLSVSK-cD4n4$ <https://urldefense.com/v3/__https://www.agu.org/agu23__;!!IKRxdwAv5BmarQ!b1haa20OxxmKLHiPC9VA0ivpkCNJXz_XdEeP0dr0P0kDiVbulvjNlAXAlITCNEXEIy_WMmRDz1WQNYC6wbp9ka3LgZymh-E$> . We look forward to an interesting and engaging session and hope to see you there!
