PHY3102 GEOPHYSICS II 1. 2. 3. 4. Course Name : Geophysics II Course Code/Level: PHY3102 Credit hours : 2 Course Description This is a continuation of Geophysics I. The general aim of the course is to explain the basic principles of the different geophysical methods – gravity, magnetic, electrical and electromagnetic - and their use in locating resources such as hydrocarbons and metallic minerals, groundwater and litho logical mapping. 5. Course Objectives By the end of the course the student should be able to: Describe the most important geophysical methods used to determine physical subsurface properties; Discover minerals of economic interest through analysis; Specify the most appropriate technique(s) to solve any particular geological problem; Design and execute geophysical survey for a given area; and Process and interpret geophysical data. 6. Course Outline: Content General survey of applied geophysics methods and field practice: rock properties, geophysical methods and survey environment. Applications of geophysical methods: geological mapping, oil and gas exploration, mineral exploration, ground water and engineering geology. Phases of geophysical survey. Gravity method: gravity meters, data reduction, drift and tidal; data presentation and applications. Magnetic methods: magnetometers, data reductions, data presentation, applications. Electrical methods: resistivity, induced polarization, applications. Electromagnetic methods: Principle, theory and measurements, and applications. Total hours 4 6 2 6 4 4 4 30 7. Mode of Delivery: This course is mainly lecture based, with occasional tutorials to allow for student-lecturer interaction and solving problems together. 8.
