根据热点假设,热点对于中间层是固定的。相对热点的板块运动叫做绝对板块运动。绝对板块运动模型可以通过反演火山链传播的速率和走向数据以确定相对板块运动在角速度空间的原点来得到。利用一组近来(0～7.8Ma)全球分布的热点的迁移速率和走向数据,结合板块运动模型NNR-NUVEL1A,已研制出一个叫做APM2的现今绝对板块运动模型。按照该模型,太平洋板块围绕60.063°S、102.210°E处的极以(0.8330°±0.0133°)/Ma的速率运动,非洲板块围绕46.849°N、44.372°W的极以(0.1015°±0.0134°)/Ma的速率运动,南极板块的运动则以46.871°N、146.942°E为极,速率为(0.0846°±0.0177°)/Ma,欧亚板块的运动更慢,极为27.291°N、171.925°W,速率为(0.0655°±0.0206°)/Ma。这一模型表明,岩石圈相对深部地幔有一个以49.423°S、90.625°E为极,速率为(0.1983°±0.0135°)/Ma的净旋转。表明太平洋热点同印度—大西洋热点不一致,显示太平洋热点的运动也不一致。为了分析和比较,还给出了仅用全球分布的热点的走向数据和仅用印度-大西洋热点的走向数据得到的板块绝对运动的角速度。
According to the hot point assumption, the hot spot is fixed to the middle layer. The relatively hot plate movement is called absolute plate movement. The absolute plate motion model can be obtained by inverting the velocity and direction of volcanic chain propagation to determine the origin of the relative plate motion in the angular velocity space. Using a set of recent hot migration rates and direction data (0 ~ 7.8Ma) globally, combined with the plate motion model NNR-NUVEL1A, a current absolute plate motion model called APM2 has been developed. According to the model, the Pacific plate moves at a rate of (0.8330 ° ± 0.0133 °) / Ma around 60.063 ° S at 102.210 ° E, and the plate of Africa at 46.849 ° N, with a pole of 44.372 ° W at (0.1015 ° ± 0.0134 ° ) / Ma. The movement of the Antarctic plate at the pole of 46.871 ° N and 146.942 ° E is at a rate of 0.0846 ° ± 0.0177 ° / Ma. The movement of the Eurasian plate is much slower at 27.291 ° N and 171.925 ° W at a rate of (0.0655 ° ± 0.0206 °) / Ma. This model shows that the relatively deep mantle in the lithosphere has a net rotation of 49.423 ° S and 90.625 ° E at a rate of (0.1983 ° ± 0.0135 °) / Ma. This shows that the Pacific hot spot is inconsistent with the Indian-Atlantic hot spot and shows that the Pacific hot spot movement is also inconsistent. For the purpose of analysis and comparison, the angular velocity of plate absolute motion using only the globally distributed hotspots and the strike data of the Indo-Atlantic hotspots is also given.
