THE FEASIBILITY OF THE AIRBORNE FLUXGATE MAGNETOMETER AS AN EXPLORATION TOOL - RESULTS FROM THREE DIMENSIONAL NUMERICAL MODELLING

The earliest geophysical exploration strategies relied on measurements of variations in the Earth's magnetic field. Even today, magnetic methods are the most commonly used geophysical exploration techniques because magnetic observations can be made relatively easily and cheaply. Although compasses are the most common type of mechanical device used to measure the horizontal attitude of the magnetic field, other
