稳态热传导,重力,地震波折射,瞬时热传导以及动态热力学结构奠定了格兰德河裂谷岩石圈和软流圈已有的地球物理和数值模式的基础。本文提出的有限单元模式,要解决的是大陆裂谷作用过程中地幔增温对后成隆起、地壳的扩张和拉伸的影响问题。地幔对流的热传递限制在半固体流动或蠕动范围内,因此就不考虑熔化和相变的作用。地壳和地幔被看作是连续的,放不考虑断层作用的影响。本文将集中 Steady-state heat transfer, gravity, seismic refraction, instantaneous heat conduction, and dynamic thermodynamic lay the foundations for the existing geophysical and numerical models of the Rio Grande rift lithosphere and asthenosphere. The finite element model proposed in this paper is to solve the problem of the effect of mantle warming on the uplift and crustal expansion and stretching during the continental rifting. The convective heat transfer in the mantle is confined to a semi-solid flow or peristaltic range, so melting and transformation are not considered. The crust and mantle are considered as continuous and do not consider the effects of faulting. This article will focus
