Possibility of Investigation of Kimberlite Pipes by Superconductive Geomagnetic Variation Measuring Stations

摘要

Tests to study the possibilities of investigating kimberlite pipes by means of superconductive geomagnetic variation recording stations with three-component magnetometers and Josephson contacts and with a sensitivity of 10(-8) ergs in the 10(-3) - 1 Hz frequency range and a zero-point stability of not less than 2.10(-8) ergs/hour, confirmed the phenomenon of quantum interference with superconductor contours. This effect is of great value in determining kimberlite pipe boundaries: contouring, determination of magnetic susceptibility of kimberlite, etc.
