Identification of geochemical markers of the halo projection of deep-seated ore bodies based on the results of sampling the snow cover (using the example of the Turuntaevsky polymetallic deposit)

The paper considers the possibility of using the step centrifugation method to detect the halo projection of deep-lying ore bodies using geochemical markers, which are trace elements from three paragenetic groups: sulfophiles, siderophiles and lithophiles. The paper presents results of comparative studies of the distribution of trace elements in centrifugates of snow water samples obtained at different rotation speeds. The information content of the new method is assessed as applied to geochemical surveys of snow cover, taking into account the microphysical properties of snow. The epitaxial mechanism of amplification of the signal of trace element concentration in snow grains and the related features of the formation of geochemical anomalies in the snow mass are discussed.
