Dear Colleagues, We invite proposals for sessions in Theme 07 ”Mineral, Melt and Fluid Chemistry" at the Goldschmidt 2020 in Honolulu (Hawaii) next June. The theme description is given below and proposals can be submitted at: https://goldschmidt.info/2020/callForSessions The *deadline* for session proposals is in a week: *18 October 2019*. Look forward to your session ideas, and hope to see you Hawaii! Clara Chan, Aaron J. Cavosie, and Carmen Sanchez-Valle _Theme 7_ Mineral, Melt and Fluid Chemistry Minerals and fluids are primary components of Earth and planets, from atmosphere to core. Their formation and reactions drive geologic processes, leaving signatures embedded in minerals. The chemistry and structure of minerals are fingerprints of mineral interactions with other minerals, fluids, melts, atmosphere, and biosphere. Deciphering these signatures using new techniques has allowed unprecedented insights into planetary evolution. We solicit sessions on mineral, melt and fluid chemistry and physics, with topics such as biomineralogy, fluid and melt chemistry and evolution, deformation and phase transformations, mineral-fluid interactions, crystal structure and chemistry, thermodynamics of processes and novel techniques and applications. -- Clara Chan College of Earth, Ocean and Environment, University of Delaware (302) 831-1819 Delaware Biotechnology Institute (DBI) office: room 120D, lab: room 146 Please send packages to: DBI, 15 Innovation Way., Newark, DE, 19711 Interdisciplinary Science and Engineering (ISE) Lab office: room 470, lab: room 455 http://udel.edu/~cschan/Site/Home.html Twitter: @microbestalker
