Abstract

The capacitites of the geophysical methods in prospecting and exploration of gold placers in complex geological conditions of the Far Eastern region of Russia are analyzed. It is shown that the main methods for studying the alluvial placers structure, and in some cases, identification of gold deposits are various modifications of electrical prospecting. These methods include the electrical sounding techniques VES and VES-IP as the most effective of those used in the Far East conditions. The latter modification features increased resolution in detecting of gold deposits enriched with sulphides. At the stage of prospecting and exploration of at the depths over 30 m, the volume of geophysical operations is substantially increased. Typical geoelectric sections for selected promising areas and the conceptual model of the section have been developed for field data interpretation. The influence of water and clay contents on the resistivity values of loose sediments in the geoelectric section is shown. The case studies of geophysical investigations with reinterpretation of electrical sounding data obtained in typical promising areas in the Amur Region, and the Khabarovsk and Primorye Territories are presented. They prove sufficiently high efficiency of the electrical prospecting in combination with magnetic prospecting and seismic survey.
