The article contains the results of statistical processing of geochemical data for rocks of the Porokhovskoe tungsten deposit (South Urals) obtained during systematic geological exploration. Statistical samplings were formed for various types of host rocks: andesites and their tuffs, shales, metasomatites (includ¬ing sericite-quartz, epidote and chlorite-bearing) and skarns. It is established that all rocks of the Porokhovskoe deposit are characterized by increased contents of W and Mo and, to a lesser extent, Be, Cu, Li, and Zn and by stable groups of correlated elements, both associated with greisenization process and those inherited from the protolith. No zoning is revealed in the distribution of elements in relation to the Yugo-Konevsky leucogranitic pluton, which is considered the ore-generating for the deposit. No correlation between W and Mo was identi-fed in all types of host rocks. A number of statistical methods is proposed for the identifcation of promising areas with unclear W-Mo mineralization in rocks.
Keywords: tungsten, metasomatites, greisenization, statistical analysis, Porokhovskoe deposit, South Urals.
