Structural Geology- Introduction Introduction Structural geology is the study of deformed rocks, and rock deformation. In structural geology, we are faced with a series of natural features that we try to interpret and explain. Each of these features formed through the interplay of external forces on rock materials, and the \local \conditions at the time of deformation. To interpret structures in the natural setting we need to

Atomic Structure All natural and most synthetic substances on earth are made from the ninety naturally occurring chemical elements. An atom is the smallest particle into which an element can be divided while still retaining the chemical characteristics of that element (fig 3. 1). The nucleus, at the center of the atom contains one or more particles with a positive electrical charge(protons fif and usually some particles of similar mass that have no charge(neutrons

1、早期的太阳系 The Early Solar System Billions of years ago, out of a swirling mass of gas and dust, evolved a system of varied planets hurtling around a nuclear-powered star-our solar system. One of these planets, and one only, give rise to complex life forms. Over time

同位素:指元素周期表中原子序数相同,原子量不同的元素。 稳定同位素:指原子核的结构不会自发的发生改变的同位素。 稳定同位素有两个最显著的属性: 1.稳定性:即经过复杂的化学反应之后,原子核结 构不发生变化。 2.分馏作用:指同位素在两种同位素比值不同的物质之间进行分配

Brokenback feature in Wyoming. Interpret the fracture pattern using your o 1. The following map shows the principal azimuths for fractures measured on th knowledge of joints and joint systems. Prepare a written(1 paragraph) analysis detailing the \joint system\these fractures may represent. Be sure to include a discussion of your evidence in support of your conclusion
