This work will test the following hypotheses: (1) Pacific hotspot trails reflect several second-order changes in absolute plate motion that can be correlated among the long-lived hotspot chains, (2) the times of absolute plate motion changes correlate with changes in relative plate motion, which seem to have been precipitated by circum-Pacific tectonic events, so times of relative plate motion changes can constrain absolute plate motion models; and (3) absolute plate motion changes may trigger not-spot intraplate volcanism that will contaminate the age-progressive hotspot trail data set. A detailed model for the Pacific absolute plate motion back to 65 Ma will be developed.

这项工作将检验以下假设：（1）太平洋热点尾迹反映了板块绝对运动的若干次二级变化，这些变化在长寿命热点链之间可以相互关联;（2）板块绝对运动变化的时间与板块相对运动的变化相关，这些变化似乎是由环太平洋构造事件促成的;因此，相对板块运动变化的时间可以限制绝对板块运动模型;和（3）绝对板块运动变化可能会触发非点板内火山活动，这将污染年龄渐进热点轨迹数据集。 一个详细的模型，太平洋绝对板块运动回65马将开发。
