Abstract.

According to the observations of natural impulse electromagnetic field of the Earth, tectonic disturbances and linear residual soils were detected in the Sergeevskoye deposit area and Solnechnoye ore occurrence area. Dominating azimuths were defined for the tectonic disturbance and linear residual soil strikes. Types of gold mineralization were specified which are confined to the fracturing disturbances and linear residual soils. Relationship between level of the observed natural impulse electromagnetic field of the Earth and gold mineralization was determined for zones with tectonic disturbances and linear residual soils of various types.

The results obtained were used in preparing opinions on the gold content in the Solonyanskoye  ore field (Sergeevskoye deposits) and Solnechnoye ore occurrence area.

Conclusions – Basing on the observations of natural impulse electromagnetic field of the Earth, schematic maps of the flux density were built for some districts of the Sergeevskoye deposits and Solnechnoye ore occurrence area. Key azimuth lines were built for further dynamics of tectonic disturbances and linear residual soils development. Interdependence was established between level of electromagnetic field and gold mineralization for the selected types of the gold mineralization manifestation: y = 0,945x + 0,270; R² = 0,965 (for the Sergeevskoye field), position of vein zones to which gold mineralization trends to develop: y = 0,4x + 2,1; R² = 0,996 (for Solnechnoye ore occurrence area). This method can be recommended as an additional prognostic indicator in identifying zones with high gold mineralization.

Keywords:

tectonic disturbances, linear residual soils, natural impulse electromagnetic field of the Earth, gold mineralization.
