本文的主要目的是提出一种地幔对流的新模型,能够兼顾研究地幔对流的两种方法,即板块构造运动和热对流运动的研究方法。与板块构造研究一样,冷的俯冲板块的负浮力被认为是地幔对流的主要驱动力。物质的粘度的空间分布由于极易受温度的影响,这种性质决定了地幔对板块向下运动所产生的反应。这个论点会导致建立等粘性的地幔内发生流动简单动 The main purpose of this paper is to propose a new model of convection in the mantle, which can be used to study two methods of convective mantle convection, ie tectonic movement and convection movement. As with plate tectonics, the negative buoyancy of cold subducted slabs is considered as the main driving force of mantle convection. The spatial distribution of the material’s viscosity, which is highly susceptible to temperature, determines the response of the mantle to the downward movement of the plate. This argument leads to the simple movement of the flow in creating a viscous mantle
