Collaborative Research on Ocean Ridge - Hot Spot Interactions and Their Implications for the Structure of Oceanic Plateaus

林9302915 PI将分析地球物理数据，并对加拉帕戈斯热点数据进行建模，以了解热点如何与扩散中心相互作用。 这是目前在加拉帕戈斯建立测深和重力模型的工作的延伸。 将进行三维模拟实验，以探索粘度变化、压力梯度和流动力对羽流夹带和分散、温度结构和熔体生产的影响。 该模型将用于计算地壳超厚、深度异常、重力异常和弹性板块厚度的变化。 总的目标是更好地了解地幔动力学的脊lume相互作用。

Lin 9302915 The PIs will analyze geophysical data and perform modelling on Galapagos Hot Spot data to understand how hot spots interact with a spreading center. This is an extension of the current work on modelling bathymetry and gravity in the Galapagos. A 3-D modelling experiment will be performed to explore the influences of viscosity variations, pressure gradients and buoyance forces on plume entrainment and dispersion, temperature structure and melt production. The model will be used to calculate excess crustal thickness, depth anomalies, gravity anomalies and variations in the elastic plate thickness. The overall goal is to better understand mantle dynamics of ridge-lume interactions.
