| Course Description |
| GRAVITY PROSPECTING: Principles of Gravity, Newton's Law of gravitation, gravitational potential, potential field equations. The
gravity field of the Earth, geo-potential, geoid, spheroid, international gravity formulas. Methods used in measuring the absolute
value of gravity measurements of gravity difference (gravimeters), measurement of gravity on Land, at sea and in the air,
reductions, and corrections applied to measured gravity values. Types of gravity anomalies met in practice. Methods and techniques
used in the separation of regional and residual anomalies on gravity and magnetic maps: design of numerical filters, filtering in
space and wave-number domains, methods of analytical continuation, horizontal and vertical derivatives. Estimation of total
anomalous mass. Gravity anomaly formulas of the bodies having different geometric forms. Interpretation of gravity anomalies by
the method of characteristic curves. MAGNETIC PROSPECTING: Physical basis of the method, dipole field, and its properties. Field
operations, instruments used in field operations, magnetic effects of various model bodies in the presence of Earth's magnetic field.
Interpretation of magnetic anomalies by the method of characteristic curves. Calculation of magnetic anomalies of randomly shaped
bodies using Talwani's method. |
