12. 3 the main substance about engineering geology
(工程地质学研究的具体内容)
The purpose of studying GE is to provide good geological environment for engineering or to evaluate and forecast the engineering geological problems that may occurred in the period of the service time（服务期） of the building. on this base, to give the effective engineering prevention methods.

13. Geological environment (geological condition)
1 ◆ the study about topography and landforms
（地形地貌）
2 ◆ the study about the fundamental engineering
properties(physical and mechanics) of soils
and rock(岩土性质）

15. Chapter 1
The basic information of
earth(地球的基本知识)

16. SECTION 1-1 Inner structure of earth
地球的内部结构

17. The Crust(地壳)
This region is thin compared to the other layers in the Earth.  It varies in thickness from 10km deep to 65km deep.  The crust is made up of lighter rocks that "float" on top of the mantle. This layer includes the continents as well as the rock under the oceans.  we have built many deep mines but NONE have yet reached the mantle!

18. 软流圈
岩石圈
上地慢

19. 有关岩石圈 (lithosphere)
Structure of the Earth‘s crust and top most layer of the upper mantle（上地慢）. The lithosphere
（岩石圈） consists of the oceanic crust, continental crust, and uppermost mantle. Beneath the lithosphereis the asthenosphere（软流圈）. This layer, which is also part of the upper mantle, extends to a depth of about 200 kilometers. Sedimentary deposits are commonly found at the boundaries between the continental and oceanic crust.

20. The Mantle（地幔）:
This region lies under the crust and is approximately 2900km thick.  The mantle is much denser than the crust (which is why the crust floats on top) and has a texture much like tar.  The rock in this region is rich in compounds made from iron, magnesium, and silicon which accounts for why it is denser than the crust.

21. The Core:
This region is divided into two parts.  The outer part is called the Outer Core.  It is about 2100km thick and made of liquid nickel and iron.  The inner part is called the Inner Core and it is the real centre of the Earth.  This part is about 2800km in diameter and is made of solid iron and nickel.

30. SECTION 1-3 :The concept of Geological Action
地质作用的概念
1 What is geological action:
mean the actions that make alteration for the
composition ， structure, shape of the rock cycle
because of the natural dynamics.
Crust movement
Sun
natural dynamics Wind
glacier
gravitation
water

31. 2        The classification of the Geo. Action
（地质作用分类）
(1) outer-dynamics geological action(外动力地质作用)
dynamic source is from the sun , gravity, attraction
force between sun and moon.
▶ Weathering（风化作用）
→the Rock is destroyed at the place where it was
formed because of the outer dynamics .
▶ Erosion（剥蚀作用）
→ Rock body 岩体 is separated from its mother rock
（母岩）because of the water, wind, glacier.

32. ▶ Carrying(搬运作用)
→the process that rock is carried from one place
to anther place. Because of…
▶ Sedimentation（沉积作用）
→ the process in which the carrying materials
sink to the bottom of ground when the power
of gravity of the materials is bigger than the
carrying force.
▶ Rock-formation action（成岩作用）
→the process that the materials sunk to ground
surface to become hard or solid rock body.

33. (2) Inner-dynamics geological action(内动力地质作用)
( the dynamics source is from earth
▶ Crust movement（地壳运动）
▶ B: Magmatism (magmatic activities)岩浆作用
(magmatic intrusion and volcanic eruption)
▶ Earthquake（地震作用）

34. ▶ Metamorphism（变质作用）
Because of the high pressure and or temperature, the rock is changed to a new kind of rock, This rock is called metamorphic rock..
Every geological phenomena is the result of geological action. Including: A mineral ,rock, Land shape (mountain, river, plain..) Tectonics
