该项目将开发和使用全球流动模型来检验地球动力学假设，包括地幔成分分层、地震层析模型与温度/成分的关系、板块运动的驱动机制及其与地幔非均质性的关系、海平面变化的起源以及深层大陆结构的演化。这些模型将根据观测到的地震和重力数据进行测试。＊＊＊＊
英文摘要
9506427 Hager The PI will develop and use global flow models to test geodynamical hypotheses, including compositional stratification of the mantle, the relation between seismic tomographic models and temperature/composition, the driving mechanism for plate motions and its relation to mantle heterogeneity, the origin of sea level variations, and the evolution of deep continental structure. These models will be tested against observed seismic and gravity data. ****
