Mantle Plume-Lithosphere Interaction: An Interdisciplinary Study of the Dynamics of the Hawaiian Hotspot

小行星9303402 热点信号的空间变异性是地幔柱动力学的一个基本特征。 这种变化最清楚地表现在离散岛屿的形成沿着夏威夷链的轴，大波长变化的大地水准面和地形的夏威夷隆起，不同的地球化学特征的火山，包括岛屿，并在双重，平行的山脊系统，存在于许多岛屿。 该项目的目的是研究地幔柱头在岩石圈下扩散和/或与岩石圈相互作用的动力学背景下这种空间变化的原因。 这将通过综合地球物理和地球化学数据分析与地球动力学建模来实现。 ***

9303402 Bercovici The spatial variability of hotspot signatures is a basic feature of the dynamics of mantle plumes. This variability is most clearly expressed in the formation of discrete islands along the axis of the Hawaiian chain, large wavelength variation in the geoid and topography of the Hawaiian swell, differing geochemical signatures of the volcanoes that comprise the islands, and in the dual, parallel ridge system that exists on many of the islands. The purpose of this project is to examine the causes of this spatial variability in the context of the dynamics of mantle plume heads spreading beneath and/or interacting with the lithosphere. This will be done through a synthesis of geophysical and geochemical data analyses with geodynamical modelling. ***
