Overview

This course provides a simplified definition of geophysics. It deals with definitions and applications of various geophysical methods, namely: gravitational, magnetic, electrical, electromagnetic, seismic, and well logging recordings. It also clearly states:

  • Knowledge of geophysics and its relationship to geology.
  • Study the basics of geophysical methods used in exploration and the laws on which each method depends.
  • Knowing the basic elements that make up the Earth, and the contribution of geophysics to exploring and clarifying the depths of the Earth.

Intended learning outcomes

a. Knowledge and understanding:

1. The student will be familiar with the basic concepts of all geophysical methods used in prospecting.

2. Giving the student an experience in knowing the physical properties of the earth and the methods used to know them.

3. The student will be familiar with the devices used in some geophysical methods and be able to use them.

B. Mental skills:

1. Conducts and proposes the necessary measurements to reach the best result in exploration.

2. He can process the measurements that he previously collected during the simplified survey, in order to make corrections.

3. Employ the available information to interpret geophysical data to prepare a report and train himself to write in a proper form.

C. Practical and professional skills:

1. Dealing with geophysical measurement devices and discovering their faults.

2. Use relevant laws in every way to interpret geophysical information.

3. He can compare the results of geophysical methods to study geological phenomena.

D. Generic and transferable skills:

1. Gaining the ability to develop his skills in measurement and interpretation.

2. Discussion in a scientific manner.

3. The ability to present data in a scientific way.

Teaching and learning methods

  • Theoretical lectures.
  • Practical lessons.
