课程简介（教工部数据）
地球科学研究的目的之一是理解地球演化的机制。地球物理学、地球化学、地质学等学科为我们理解地球演化的动力学机制提供了必不可少的，但是时空碎片化的，且具有误差的观测。地球动力学旨在以基本物理化学规律为限制，构建一个简单的，但是能够统一各学科观测的模型。本课程首先介绍地球动力学的基本研究思路与方法；之后，对地球的内部结构、热状态、形状与重力场等进行了简单的介绍，并穿插地介绍了板块构造与地幔柱、地幔对流、岩石圈板块挠曲模型、断层作用等重要地球动力学模型。
Understanding the mechanism controlling the Earth’s dynamic evolution is one important goal in Earth Sciences. Geophysics, Geochemistry, Geology and other subjects provide vital but spatially- and temporally-fragmented observations that have large uncertainties. Constrained by basic physical and chemical rules, Geodynamics aims at building simple models that unify various observations. During this course, the lecturer will first introduce the basic research strategies and methods of Geodynamics. Following that, the lecturer will briefly introduce the internal structure, thermal state, and shape and gravity field of the Earth. Several important geodynamic models, including plate tectonics, mantle hot plume, mantle convection, lithospheric flexure, faulting will also be introduced during this course.
