The Dynamics of Plume-Ridge Interaction

这项工作解决了与轴上和离轴地幔柱如何与脊线相互作用（热、化学和动力学）有关的问题，适用于未分段与分段扩展几何形状的情况，以及脊线相对于地幔柱源迁移的情况。羽脊相互作用的流体动力学将通过实验室和数值模拟技术的结合得到约束。在计算熔体体积和化学、轴向测深和重力的轴向模式的数值模型中增加子分量，将为进一步限制地幔过程提供预测能力。

9618315 Kincaid This work addresses questions related to how on- and off-axis mantle plumes interact (thermally, chemically, and dynamically) with ridges for cases of unsegmented versus segmented spreading geometries and for cases where the ridge migrated relative to the plume source. The fluid dynamics of plume-ridge interaction will be constrained through a combination of laboratory and numerical modeling techniques. The addition of sub-components to the numerical models that calculate axial patterns in melt volume and chemistry, axial bathymetry and gravity will provide a predictive capability for further constraining mantle processes.
