Abstract
In the various methods of geophysical prospecting, sensitive instruments are used on or near the surface of the earth to measure effects which arise from differences between the physical properties of rocks, ores and minerals. The analysis and interpretation of these measurements permit conclusions to be drawn concerning the sub-surface geology and the presence or absence of orebodies, coal seams, and the like, or of structures likely to be favourable to the occurrence of oil, etc. The principal physical properties of rocks which are useful in geophysical prospecting are density, elasticity, electrical conductivity, radio-conductivity and magnetic susceptibility. Aeromagnetic survey methods, their present use, and results of such surveys, are discussed in this report.
