Science Degree Program in China - Geophysics

1. Introduction

Geophysics is one of the major disciplines of earth science, a comprehensive subject through the quantitative physical methods (methods such as: seismic elastic wave, gravity, geomagnetism, geoelectricity, geothermal and radiation energy) to study the earth and looking for mineral resources of the earth interior, the scope of the study includes the earth's crust, mantle and core and atmosphere. Geophysics has many branches of study, including: solid earth physics, geodynamics, seismology, geodesy, geothermics, geomagnetism, hydrological geography, oceanography, meteorology, core tectonics and geophysics, comparative planetology, tectonophysics and geodetic astronomy; research contents include the internal structure of the earth, theoretical source, seismic wave propagation theory, characteristics of continental crust in large scale, such as plate subduction zone and the mid ocean ridge. Traditional geophysics mainly refers to the solid earth physics and modern geophysical research extends to outside the earth's atmosphere phenomena (such as ionospheric dynamo, auroral electrojets, magnetopause current system), and even extends to the physical properties of the planets and their satellites.

2. Research Content

The research content of geophysics can be divided into two categories: applied and theory geophysics. The research scope of applied geophysics (also known as exploration geophysics) is quite extensive, mainly including energy exploration, metal and nonmetal exploration, environment and engineering exploration, etc. Exploration geophysics uses the development of geophysics method for prospecting and looking for oil, engineering and environmental monitoring, and structural studies. Methods including seismic prospecting, electrical prospecting, gravity survey, magnetic prospecting, geophysical well logging and radioactive exploration, through advanced geophysical measuring instruments, measurements from underground geophysical information, the information of the measured for analysis, processing, inversion and interpretation, thus it can be inferred that underground structure and distribution of mineral resources. Exploration geophysics is the main subject of the reconnaissance and detection of oil, metal and non-metallic deposits, groundwater resources and large-scale engineering foundations.

3. Important Concepts

Generally speaking, geophysics is the science that uses physical methods to study the earth and other planets, various physical properties of earth, including the earth's interior and surface composition and the function of all kinds of natural and the change rule of. The fields can be distinguished by the following categories:

1) Seismology

Research on earthquake, seismic wave and the science of earthquake related in the earth's interior, one of the most important scientific seismology is used to study the internal structure of the earth.

(2) Gravity

The science that studies the earth's gravity, studies the earth's gravity, gravity distribution, gravity field and other related properties.

(3) Geomagnetism

Study the magnetic properties of the earth and atmosphere, mainly study the magnetic phenomena, sources, magnetic fields and so on.

(4) Geoelectricity

The science that studies the earth's electric field in order to deduce the physical properties, composition and distribution of the earth's interior.

(5) Geothermometry

Study the earth's thermal, including the earth's temperature, internal heat flow, the distribution of surface temperature and the source of the earth's heat energy, etc.

6) Geophysical Prospecting

This is the use of geophysical techniques, including earthquake, geoelectro, gravity and geothermal, can be used in mining and exploration of oil, metal and non-metallic deposits, groundwater resources and engineering foundations.
