Workshop on Minerals-Water-Organics
in the Early Solar System

May 18-19, 2012
TKP Tokyo Station Business Center #1 (Room 5B: 5th floor)
Tokyo, Japan

Recent progress in the study of primitive materials in the early solar system such as chondrites, interplanetary dust particles, micrometeorites, comets and asteroids, shows that chemical interaction between inorganic minerals, organic materials, and water is crucial in their evolution.  This workshop aims at providing opportunity to discuss and share current status and future perspectives in the research of evolution of minerals, water, and organic materials in the early solar system.  The same topic will also be discussed at the JpGU2012 meeting in May 20 (Sun).
