地球内部的热传输

Heat transport within the Earth

J. Marvin Herndon

摘要:

许多人试图解释地球的动力学过程的基础上的热传输概念来自普通的经验。但是,普通的经验可能是误导性的,特别是当被错误的假设所支撑时。地球动力学的考虑传统上包括三种热传输模式:传导、对流和辐射。最近,我介绍了第四种现象,即“地幔减压热海啸”,我认为,这是地壳底部热量就位的原因。在这里,我回顾了地球内部的热传输,并推测可能存在第五种模式:“热通道”,涉及从核心到“热点”的热传输,如夏威夷群岛和冰岛。

英文摘要:

Numerous attempts have been made to interpret Earth's dynamic processes based upon heat transport concepts derived from ordinary experience. But, ordinary experience can be misleading, especially when underlain by false assumptions. Geodynamic considerations traditionally have embraced three modes of heat transport: conduction, convection, and radiation. Recently, I introduced a fourth, "mantle decompression thermal tsunami" that, I submit, is responsible for emplacing heat at the base of the Earth's crust. Here, I review thermal transport within the Earth and speculate that there might be a fifth mode: "heat channeling", involving heat transport from the core to "hot-spots" such as those that power the Hawaiian Islands and Iceland.
