Intellectual Merit The work proposed is to develop quantitative tools to model fluid flow and magmatism at subduction zones. The focus of the work will be on the top of the downgoing slab where fluids are released by metamorphic dehydration reactions, and the mantle wedge where fluids interact with high temperature solids to form magma. The work will start with 2-D models and extend to more challenging 3-D models. Broader Impacts This project will contribute to the modeling infrastructure of the marine geology and geophysics community and other communities as well. It will also address the need for the synthesis of geochemical and geophysical observations as the MARGINS program enters its final stages. Finally, it will support a full-time post-doc.

智力价值 拟议的工作是开发定量工具来模拟俯冲带的流体流动和岩浆作用。这项工作的重点将是下行板片的顶部，其中流体通过变质脱水反应释放，以及地幔楔，其中流体与高温固体相互作用形成岩浆。这项工作将从 2D 模型开始，并扩展到更具挑战性的 3D 模型。更广泛的影响 该项目将为海洋地质学和地球物理学界以及其他界的建模基础设施做出贡献。随着 MARGINS 计划进入最后阶段，它还将满足综合地球化学和地球物理观测的需求。最后，它将支持全职博士后。
