COMPUTATIONAL GEODYNAMICS OF THE PACIFIC OCEAN AND PACIFIC MOBILE BELT

An abbreviated variant (condensed and updated by an American specialist) of a research monograph focuses on the gravity field, geoid height, seismicity, rheology, and Phanerozoic tectonic history of the Pacific Ocean and the surrounding Pacific Mobile Belt from a computational geodynamic perspective. The state of stress calculated for the Pacific Mobile Belt incidates that it is a geologically persistent tectonic boundary separating the Pacific hemisphere from the Indo-Afro-Atlantic hemisphere, which contains the bulk of the earth's continental crust. The gravity field of the Pacific Basin has a concentric structure and the region has a counter-clockwise sense of rotation relative to the Pacific Mobile Belt and surrounding hemisphere. The relative displacement is believed to have been approximately periodic through Phanerozoic time.
