Factors of Localization and Forecasting of Ore Mineralization in the Dzhusa Pyrite–Polymetallic Deposit (Southern Urals)

An analysis of tectonic displacements along fractures and faults revealed changes in the character of tectonic deformations that resulted from tectonic evolution of the Magnitogorsk island arc. Structural conditions of localization of ore mineralization of various types were investigated in the open pit of the Dzhusa deposit. The block diagram of an ore shoot of the Dzhusa deposit, which is confined to intersection of NW-striking and sublongitudinal faults was constructed. Trends in the distribution of sites with enriched mineralization are slightly different for various metals. The obtained data make it possible to predict the localization of rich ore bodies at deeper levels of the deposit and to reveal new prospecting ore sites in the Terensai ore field.
