geophysical exploration may be defined as prospecting for mineral deposits and geologic structure by surface measurement of physical quantities geophysical exploration (GE) makes use of phenomena which can be interpreted fully through the fundamental laws of physics, measured, and verified by anyone as long as suitable instruments are used geophysical exploration may be considered an application of the principles of geophysics to geological exploration derived from the Greek the word Geophysics means “physics” or “nature” of the earth it deals with the composition and physical phenomena of the earth and its liquid and gaseous envelopes it embraces the study of terrestrial magnetism, atmospheric electricity, and gravity; and it includes seismology, volcanology, oceanology, meteorology, and related sciences experience has demonstrated that most subsurface structures and mineral deposits can be located, provided that detectable differences in physical properties exist the main properties exhibited by the more common rocks and formations are: density, magnetism, elasticity, and electrical conductivity this entails for major geophysical methods: gravitational, magnetic, seismic, and electrical since GE is the determination of subsurface geologic structure by means of surface physical measurements, it is applicable in industrial fields where knowledge of geologic conditions is essential it is understood that such applications are advisable only where structures and ore bodies are not exposed, as most geophysical measurements are more expensive than surface geological surveying
