Аннотация

In the mountainous conditions of the Eastern Sayan on the flangs of one of the quartz-gold sulfide deposits, electrical exploration was performed using the method of electro resistivity tomography with measurement of the induced polarization. The main goal of the research is mapping of ore control structures and tracing them to depth. With the help of special devices, the step between electrodes from 5 to 10 m was increased with the use of standard cables. This made it possible to obtain a geoelectric model to a depth of 200-230 m. Known ore control zones of cataclasis and mylonitization are traced by linear anomalies of low electrical resistivity. In the near-contact parts of these zones, an increased polarizability of rocks associated with sulfidization is established. A geoelectric anomaly was discovered, interpreted as an unknown ore zone.
