Geodynamics : progress and prospects

About The Product Published by the American Geophysical Union as part of the Special Publications Series . In 1970 the President of ICSU invited member countries to establish national committees for the Geodynamics Project. At the same time the Inter-Union Commission on Geodynamics was established to administer the activities of the Project. To implement its activities, the ICG established ten Working Groups that are not organized as listed below: 1. Geodynamics of the Western Pacific-Indonesian region. 2. Geodynamics of the Eastern Pacific Region, Caribbean and Scotia arcs. 3. Geodynamics of the Alpine-Himalayan Region, West. 4. Geodynamics of Continental and Oceanic Rifts. 5. Properties and Processes in the Earth's Interior. 6. Geodynamics of the Alpine-Himalayan region, East. 7. Geodynamics of Plate Interiors. 8. Convections between Continental and Oceanic Structures. 9. History and Interaction of Tectonic, Magmatic and Metamorphic Processes. 10. Global Syntheses and Paleoreconstruction.
