Abstract:

Recent progress in several aspects in the study on the Earths deep interior are discussed, with reference to the international conference on the American Geophysical Union (AGU) Fall Meeting in 2007.The scientific problems involved vary from the comprehensive testable predictions of geodynamic models to the equation of state theories and experiments, from mantle phase transitions and seismic discontinuities to mechanisms of deep earthquakes, from structure and dynamics of Earths core to volatiles and melts in the Earths interiorAll major fields in the study of Earths deep interior are under discussion.The conference suggests that: (1)The merge interdisciplinary is a major trend in the development of the Earths deep interior study; (2)International cooperation becomes a new highlight in the research of the Earths deep interior sciences; (3)Highly precise technique (modern supercomputers and clusters) is a new way of understanding the Earths deep interior sciences; Chinese geoscientists should pay more attention to the frontiers of Earths deep interior sciences, join the noted international conference and share the advanced knowledge.
