METHOD FOR REMOTELY DETERMINING HORIZONTAL COMPONENT OF MAGNETIC INDUCTION OF ROCK IN ANCIENT EPOCHS Russian patent published in 2007 - IPC G01V3/40 

FIELD: Earth physics, in particular, paleomagnetism.

SUBSTANCE: in accordance to the invention, by means of a radiolocation plant with closely positioned emitting and receiving devices, containing horizontal magnetic dipoles in their composition, impulse generator of magnetic momentums in emitting device and Squid-magnetometer based on Josephson effect in receiving device, rotation angle of φ signal polarization plane is measured on its route to reflective boundary in the shoe of level being studied or in it and back in substance with magnetic induction B_z, coinciding with signal expansion direction. After spacing the emitting and receiving devices for a sufficient distance, which preserves possibility of registration of signals reflected from needed separation boundary, magnetization in constant magnetic field in horizontal direction in average for ΔB_H by means of horizontal magnetic dipole of the area of level being studied receiving device is moved along circle with preservation of mutual orientation of emitting and receiving magnetic dipoles and simultaneously rotation angle of polarization plane is measured. Such a position of the latter is found, at which signal polarization plane rotation angle is maximal. That means coincidence of radius, on which the receiving device is situated, with direction to the pole of the time of the epoch being studied, if in case of a different value of ΔB_H the increment of rotation angle of signal polarization plane is proportional to increment of magnetizing field.

EFFECT: increased efficiency.
