  • Method for locating sub-terranean geological aggregate deposits
    Patent number: 5214281
    Abstract: This invention relates to the field of prospecting to locate mineral deposits particularly gravel and clay deposits. The method of prospecting to locate these mineral deposits includes the steps of traversing an area of the earth's surface and obtaining measurements of gamma radiation corresponding to the presence of uranium, potassium and thorium at spaced points along the traverse. The data collected are used to determine an area mean value for the gamma radiation measurements obtained. The mineral location is obtained by noting areas within the area traversed in which the variations of the measurements of gamma radiation corresponding to each of uranium, potassium and thorium relating to the respective area mean values are indicative of the particular mineral being located.
