Whirlpool tectonics is a new view of geotectonics originally proposed by the first author. Whirlpool is one of the most ubiquitous structural features and modes of motion in the material world,and the global tectonics also exhibits whirlpool tectonics features:the lithosphere exhibits a kind of structure of whirlpool tectonics under the control of 12 stable whirlpool convection units;the evolution of global tectonics has a galactic year cycle of 187.5 Ma and a galactic year variation cycle of 750 Ma,and is periodically destroyed by galactic impacts;the overall global tectonics show a pattern of whirlpool tectonics-destruction by impacts-whirlpool recovery,repeat-ing and evolving gradually. This paper discusses the research progress of whirlpool tectonics in recent 10 years,and expounds the definition and basic views of whirlpool tectonics;the relative rationality of whirlpool tectonics is discussed by reviewing the dynamics,quantity and landings of plate tectonics;a core-mantle whirlpool convection model is proposed based on seismic tomography,magnetic anomaly age of seafloor and GPS velocity field;the significance of the earth rotation dynamics and the relationship between the whirlpool tectonics and mineralization are preliminarily analyzed. The view of whirlpool tectonics can make people think about earth science in a new way.
