洋–陆汇聚速率数值模拟结果

利用地球动力学数值模拟方法探讨洋‒陆汇聚速率影响，大洋岩石圈的绝对俯冲速率和上覆大陆岩石圈的向洋绝对逆冲速率对俯冲模式的影响， 尤其是上覆大陆的向洋绝对逆冲速率与平板俯冲之间的关系。运用I2VIS算法模拟得到较高的大洋岩石圈绝对俯冲速率更容易克服板间耦合作用力而有利于陡俯冲形成。数据包括：平板俯冲区域的主要地球动力学参数，采用的粘滞性流变参数，数值模型中的主要材料参数等。

This study employs geodynamic numerical simulations to examine the impacts of ocean-continental convergence rate, the absolute subduction velocity of the oceanic lithosphere, and the absolute oceanward thrust velocity of the overlying continental lithosphere on subduction patterns, with a particular focus on the relationship between the absolute oceanward thrust velocity of the overlying continental lithosphere and flat slab subduction. Simulations carried out using the I2VIS algorithm reveal that a higher absolute subduction velocity of the oceanic lithosphere can more readily overcome interplate coupling forces, thereby promoting the formation of steep subduction. The dataset includes key geodynamic parameters for flat slab subduction zones, the adopted viscous rheological parameters, and major material parameters used in the numerical models, among others.
