1.力和应力的概念 1.1外力和内力 处于地壳和岩石圈中的任何地质体,都会受到相邻介质的作用力

Classification of folds (continue) Based on four main features or properties: 1 direction of closing and facing 2 attitude of axial surface 3 size of inter-limb angle, and 4 shape of profile 5 dip isogons

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

Extensional Fault Systems A- Evolutionary model illustrating progressive extension accommodated by block rotation above a low-angle extensional fault. B-Listric fault with hangingwall rollover anticline. Area and B are equal. C-Flat/ramp geometry of fault produces geometrically necessary folding in hangingwall

一、纵弯褶皱作用的应变特征 1.1单层纵弯褶皱作用的基本应变特征中和面褶皱作用压扁作用

1.求两平面交线的产状 第一,据已知的两平面产状, 在吴氏网上分别求出其投影大圆弧 AHB和CID。两大圆弧的交点β即为 两平面交线与下半球面交点的投影 第二,作β与圆心O的连线, 交基圆于P点,P点的方位角即两平 面交线的倾伏向,Pβ间的角距为 交线的倾伏角

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
