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.

小行星9618315 这项工作解决了有关的问题，如何轴上和离轴地幔柱相互作用（热，化学和动态）与脊的情况下，不分段与分段蔓延的几何形状和脊迁移的情况下，相对于羽源。将通过实验室和数值模拟技术的结合来限制羽流-脊相互作用的流体动力学。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组件，将为进一步约束地幔过程提供预测能力。
