OBJECTIVES:

To understand the physics and geology that form the basis for geophysical observation and measurement; to understand earth structure and evolution. To identify the physical processes governing the behavior of common geophysical systems.

UNIT I		9

Physical Basis of Geophysical exploration – Various surface and sub surface methods and their classifications – Physical Properties of rocks and minerals exploited in exploration and factors that control them Geophysical anomalies

UNIT II		9

Gravity Prospecting – Principles – Earth Gravitational Field Units – Variations in the Gravitational field – Newton’s Law – Geoid , Spheroid and normal gravity field – Absolute and relative measurement of Gravity – Gravimeters and their field operation – Field procedure – Interpretation of Gravity data and Applications of Gravity methods.

UNIT III		9

Radiometric Prospecting: Fundamentals of radioactivity – Rate of radioactivity decay – Successive disintegration and radioactive equilibrium – Natural radioactive elements – Radio active Series – Nature of radioactive emission – Artificial radioactivity – Radioactivity of rocks. Radiation measuring devices – Processing and Interpretation data – applications of radiometric methods.

UNIT IV		9

Seismic methods, fundamentals of elasticity – bulk modulus – Poisson’s ratio – Elastic Seismic wave theory – Body and surface waves – Primary and Secondary waves – Seismic Instruments - Seismic channels – Applications of Seismic data – Interpretation of field data

UNIT V		9
