REMOTE DETERMINATION OF ZONES OF DIRECT AND REVERSE MAGNETIZATION OF ROCKS IN PAST EPOCHS

Abstract

The possibility of remote detection of the zones of direct and reverse magnetization of rocks in the past epochs related to inversions of the magnetic field is considered based on the Faraday effect in the course of radar sounding and recording of the magnetic component of reflected signals. The solution to this problem determines the moments of geomagnetic field inversion and the duration of its stable states if the age of the rocks in the section studied is known. The elements of the paleomag netic field and hence the zones of direct and reverse magnetization are traditionally determined on the basis of laboratory investigation of the residual magnetization of spatially oriented rock samples. At present, the number of such samples is possibly estimated at a few million.
