Mechanisms of Mantle Convection and Magma Migration

这项研究有两个主要目的。首先是支持首席研究员和巴黎大学Claude Allegre教授之间的合作，根据地幔对流和相关过程解释同位素和其他地球化学数据。目的是了解地幔动力学如何导致洋中脊玄武岩、洋岛玄武岩、岛弧火山作用和大陆火山作用的地球化学特征。一个重要的问题是地幔对流是否“混沌”以及混沌对流的含义。这项研究的第二个主要目的是支持首席研究员和帝国理工学院的David Spence教授在岩浆断裂机制方面的合作。

There are two main thrusts to the research. The first is to support collaboration between the Principal Investigator and Professor Claude Allegre, University of Paris, on the interpretation of isotopic and other geochemical data in terms of mantle convection and related processes. The object is to understand how mantle dynamics leads to the geochemical signitures of mid-ocean ridge basalts, ocean island basalts, island arc volcanism, and continental volcanism. An important question is whether mantle convection is "chaotic" and the implications of chaotic convection. A second major thrust of the research is to support collaboration between the Principal Investigator and Professor David Spence, Imperial College, on the mechanisms of magma fracture.
