Course Aim

After completed course, the student is expected to be able to:

• explain the concepts of geophysical models, geophysical data and anomalies
• give a quantitative account on petrophysical properties of common rock types and mineralizations
• explain the concept of equivalence by use of standard statistical tools
• describe qualitatively the Earth magnetic field
• describe qualitatively the Earth gravity field and the geoid
• explain the basic principles (physics, measuring techniques and interpretation) for the geophysical methods that are included in the course
• describe particle movements for seismic waves
• derive formulas for reflection and refraction seismic travel times for simple two layer Earth models and identify and interpret arrival time data in a seismogram
• derive formulas for reflection of radar waves for simple two layer Earth models and identify and interpret arrival time data in a radargram


Contents
Seismology-seismic profiling: The different types of seismic waves. The correlation between elastic properties of a material and P-, S- wave velocities. Reflection and refraction. Interpretation of seismic reflection and refraction data. Examples with application of refraction and reflections seismics. The magnetic field of the Earth – magnetometry: The Earth magnetic field. Magnetic properties of rocks and unconsolidated sediments. Measuring techniques and data processing. Exploration for mineral resources. The gravity field of the Earth – gravimetry: Geodesy with emphasis on the gravity field of the Earth. Density of rocks and unconsolidated sediments. Corrections to gravity data and the calculation of Bouguer anomalies. Regional/residual anomaly separation. Electric and electromagnetic methods:  Electric conductivity of rocks and unconsolidated sediments. Dielectric constants of rocks and unconsolidated sediments.  Electric methods based on natural and artificial currents. Electric sounding and mapping.  Examples in mineral prospecting, environmental studies, prospecting for and planning of water resources, pollution of ground water. Electromagnetic fields. Depth of penetration. Electromagnetic methods with examples of application in mineral exploration and environmental studies. Ground Penetrating Radar and borehole radar with examples in environmental studies. Borehole methods and logging: acoustic/sonic log; calliper log; density log; gamma log, induction/conductivity log, neutron log, resistivity log, SP-log (self-potential); temperature log; IP log (induced polarization) and magnetic log. Examples from logging in hard rock and sediments.

Realization
The teaching will be as lectures, laboratory and field training. Participation in laboratory and field training is compulsory. The lectures will be focused on basic theory and applications. The laboratory and field training will be directed on laboratory and field instrumental training, field measurements and data processing.

Examination
Written examination with differentiated degrees will be arranged at the end of the teaching period. The examination will include theory as well as problem solving. Students who have failed an examination on five occasions will not be allowed further resits.

Remarks
O0001K is equivalent to KGG001 and cannot be combined

Examiner
Thorkild Rasmussen

Transition terms
The course O0001K is equal to KGG001
