FIELD: geophysics. SUBSTANCE: method involves measurement of gravitation and/or magnetic and seismic characteristics in reconnaissance region. Gravitation and/or magnetic characteristics are translated with respect to top or bottom of target line. Then method involves calculation of derivatives of each field with respect to coordinate axes, and classification of detected objects with respect to results of mathematical processing. Presence and characteristics of deposit are judged by results of classification. EFFECT: increased precision of estimation, decreased costs. 9 cl, 9 dwg
