一、基本概念 1.地质构造的尺度;2.碎裂流动:3.压溶作用:4.断层效应;5.断层擦痕的倾伏与侧 伏;6.深成侵入岩体形成的底辟作用与气球膨胀作用;7.构造序列和构造组合;8.变质 核杂岩

就几何形态而论,任何构造都可看成是面状构造或线状构造 面状构造和线状构造都可以分成为“透入性”和“非透入性 ”两类。 透入性构造均匀地弥漫于地质体中的构造,反映地质体作 为一个整体,也均匀地发生了变形

Review Primary sedimentary structures Faults (thrust system, extensional fault system, strike-slip fault system) · Joints(tension joints, conjugate joints,en echelon joints) Folding (bending, buckling, flexural slip, flexural flow, passive folding, kinking)

REGIONAL STRESS REGIMES (ANDERSON THEORY OF FAULTING) 2 is located parallel to the fault plane, normal to the direction of slipl 3 is located normal to o, and o2/ Earth's surface is a principal plane of stress Ideal fault geometry

TECTONIC MODELING Significance of tectonic modeling History of tectonic modeling Methods of tectonic modeling General procedure of tectonic modeling

Where is stress,ε strain and the Young's modulus or elastic modulus

Review: 1.What is the orientation relationship between maximum shear stresses and principal stresses? 2. What are trajectories of principal stresses?

Force Force is a kind of mechanical action between different objects, it tends to change the shape, volume or movement state of the object with a force upon it. Force is a vector quantity, and thus possesses both magnitude and direction; it can be represented by an arrow whose length specifies the magnitude and whose
