Three-Dimensional Upwelling Beneath A Mid-Ocean Ridge

这是对形成洋中扩张中心之下地幔流动的动力过程的理论研究。将建立一个扩展中心下的三维数值模型，试图解释观察到的牛市。眼重力异常沿慢。中间和快速伸展脊的伸展脊及其缺失。这些模型将包括熔化对形成密度结构的不可逆影响，并将探索空间、温度和成分依赖流变学的影响。

This is a theoretical study of the dynamic processes shaping mantle flow beneath mid.ocean spreading centers. three dimensional numerical models of flow beneath a spreading center will be constructed to try to explain observed bulls.eye gravity anomalies along slow.spreading ridges and their absence along intermediate and fast spreading ridges. The models will include the irreversible effects of melting on shaping the density structure and will explore the effects of spatial, temperature, and composition dependent rheology.
