Abstract
Summary
The results of integrated geophysical methods application in the LS-epithermal gold deposit are presented. The work was performed in the period from 2013–2019 in Chukotka. The applied methods include gravimetric surveying, magnetic surveying, audiomagnetotelluric sounding (AMT), resistivity and induced polarization method in the frequency domain (VES-VP). The results are compared with the geology and the section of the distribution of secondary rocks alterations. Zones of increased polarizability are proposed to be used as a geophysical criterion for the presence of LS-epithermal gold-bearing veins. A technology for separating the types of secondary rocks alterations according to geophysical data is proposed.
