Volcanic and Epeirogenic Consequences of Plume-Lithosphere Interaction beneath Hawaii and Passive Continental Margins

大多数火山活动发生在板块边界、大洋中脊和火山弧上。广泛地说，在这些背景下火山活动的原因是清楚的，而发生在板块内部的李氏巨大火山活动的原因仍然不清楚。该项目将通过数值模拟和模拟(物理)模拟相结合的方法，检验这一新的假设，即沿夏威夷拱形和一些大陆边缘的板内火山活动是由上升的地幔物质羽流和上面的岩石圈之间的相互作用引起的。这一结果将有助于揭示岩石圈和下伏地幔之间的相互作用。该项目将使人们更好地了解夏威夷的火山活动，公众对此有广泛的兴趣。更广泛的影响关于这一主题的公开讲座以及对学生进行数值方法和地球动力学数值模拟的培训。

Most volcanism occurs along plate boundaries, along mid-ocean ridges and volcanic arcs. Broadly speaking, the causes of volcanism in these setting is understood, while the causes of the lee voluminous volcanism that occurs in plate interiors remain obscure. This project will test the novel hypothesis that intraplate volcanism along the Hawaiian Arch and along some continental margins is caused by interactions between rising plumes of mantle material and the overlying lithosphere by a combination of numerical and analog (physical) modeling. The results will shed light on the interaction of the lithosphere and the underlying mantle. This project will lead to better understanding of Hawaiian volcanism, in which there is broad public interest. Broader impacts public lectures on this topic and training of students in numerical methods and geodynamic numerical modeling.
