Session LanguageJJ
ScopeMany new findings in earth and planetary sciences have been obtained by using state-of-the-art techniques supported by new technical development in analytical chemistry. This session aims at providing an opportunity for those developing new analytical methods to get together and have a strategic discussion on frontiers in geochemistry and cosmochemistry. We welcome a wide range of cutting-edge geochemical topics based on technical development, which have a potential for breakthrough of earth and planetary sciences. Besides, topics related to the direction of geochemistry and cosmochemistry in future are also welcome. Especially, we welcome topics which present how to install/maintain precious facilities in geochemical laboratories. We expect wide-ranged and future-oriented discussion to develop geochemistry and cosmochemistry.
