| 旋涡构造是笔者原创提出的大地构造新观点。旋涡是物质世界最普遍的一种结构特征和运动方式，全球大地构造同样表现出旋涡构造：岩石圈在12个稳定排列的软流圈旋涡对流单元控制下表现出旋涡构造特征；其演化具187.5 Ma银河年周期和750 Ma银河年变化周期，并受到银河天体周期性撞击破坏；全球构造总体表现为旋涡构造-撞击破坏-旋涡恢复，周而复始、逐步演进的活动演化规律。本文论述近10年旋涡构造的研究进展，阐述旋涡构造定义与基本观点；通过评述对比板块构造存在的动力、数量、起源及登陆等问题，论述研究旋涡构造的必要性和相对合理性；依据地震层析成像图、海底磁异常年龄及GPS速度场等资料，提出核幔旋涡对流模式；初步分析了地球自转动力学意义、旋涡构造与成矿关系。旋涡构造观点可以使人们对地球科学进行新的思考。 |

| 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， repeating 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. |
