On the methodology of geochemical prospecting for gold deposits in Transbaikalia
Abstract
As is known, the main, if not the only, method of prospecting for gold deposits until the last decade was a schlich survey. Since 1956, in Eastern Transbaikalia and then in other areas along with the schlich survey are increasingly used geochemical methods, which became possible due to the use of highly sensitive adsorption-spectral method of analyzing samples for gold. Then electrochemical-spectral, double-arc spectral methods were proposed, among which the electrochemical-spectral method is the most widely used. All these analytical methods were developed for the analysis of lithochemical and, to a lesser extent, biochemical samples. For hydrochemical samples there are still no reliable express highly sensitive methods of gold determination. The works of VITR, Leningrad Mining Institute and other organizations have not yet left the experimental stage, although there are already some recommendations. This article is based on the materials obtained during research within the Lubavinsky ore field, as well as the materials of N. I. Safronov, V. V. Polikarpochkin and others in Eastern Transbaikalia, A. M. Grigoriev in Buryatia, L. V. Razin and I. S. Rozhkov in Yakutia ...
