Three-Dimensional Upwelling Beneath a Mid-Ocean Ridge

这是一个动态过程的理论研究 形成洋中扩张中心下方的地幔流。 三维数值模型 将建立一个中心，试图解释观察到的靶心 重力异常沿着缓慢扩张的洋脊及其缺失 沿着中间和快速扩张的脊。模特们将 包括熔化对成形的不可逆影响， 密度结构，并将探讨空间， 温度和组合物依赖性流变学。

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.
