Multidisciplinary Researches on Deep Interiors of the Earth and Planets
The study of the Earth’s deep interior has naturally focused on the core and lower mantle, which has contributed to the understanding of the history and dynamics of the Earth. Recently, however, its interest has extended to the relationship between surface phenomena and the deep interiors of planets, due to the necessity for understanding the habitability and sustainability of our planet. For convenience, the scientific questions and problems are frequently discussed in 8 categories: 1) the observational approaches to the mantle structures; 2) the dynamics of the mantle; 3) the structure and dynamics at the core-mantle boundary; 4) the composition, state and material properties of the Earth’s deep interior; 5) observational approaches to structure and dynamics of the outer core; 6) theoretical and experimental approaches to the dynamics of the outer core, especially for dynamo; 7) the structure and dynamics of the inner core; 8) the structure and dynamics of other planets. Papers are presented involving the recent progress and future perspectives from multidisciplinary research on deep interiors of the Earth and planets.
