Abstract
The invention relates to an apparatus and method for performing passive geophysical prospecting. More particularly, the present invention relates to an improved apparatus and method for locating and selected subsurface Earth material deposits or geologic formations bearing hydrocarbons, oil, gas, or commercially important ore deposits, precious metals, as a function of impulse discontinuities in the near surface atmosphere of the invention. A passive geophysical prospecting method and apparatus are provided. The apparatus has a magnetic component antenna for detecting electromagnetic radiation naturally emanating from the Earth's surface and an electrical signal from the detected electromagnetic radiation while traversing the Earth's surface by a vehicle traveling over land or water or in an airplane.
