This work covers a wide range of problems whose solution is required in order that current paradigms of melt migration (percolation, crack propagation, diapirism) can be placed on a firm foundation. This theoretical effort is complementary to existing and expected experimental efforts and geophysical data and has components of microphysics (behavior of partial melts at the lengthscale of individual grains), mesophysics (behavior at intermediate lengthscales) and macrophysics (behavior of geological systems, e.g., mid-ocean ridges, subduction zone volcanism, seamounts).

这项工作涵盖了广泛的问题，需要解决这些问题才能为当前的熔体迁移范式（渗流、裂纹扩展、底辟现象）奠定坚实的基础。 这一理论工作是对现有和预期的实验工作和地球物理数据的补充，并具有微观物理学（单个颗粒长度尺度上部分熔融的行为）、介观物理学（中等长度尺度上的行为）和宏观物理学（地质系统的行为，例如洋中脊、俯冲带火山作用、海山）的组成部分。
