METHOD FOR GEO-ELECTRICAL PROSPECTION

摘要

A geophysical method for searching and prospecting minerals is based on the 3D inversion of electrical prospection data. The conductivity of a medium is determined based on the measurement results on a basic observation system, generating a preliminary 3D model based such data carrying out a 3D calculation and calculating the offset relative to the measured data while excluding irregularities and selecting 3D objects having epicenters located under points of the basic observation system. This results in a precise 3D mode locating conductivity anomalies. Further measurements along the profiles extending through centers of the isolated anomalies can be effected, and used to correct the existing 3D model after which the presence of conductivity anomalies is confirmed or rejected and the parameters thereof are determined. The dimensions of the anomalies can be estimated and measurements made based thereon to obtain final geo-electrical 3D model of the medium being studied.
