On the nature, composition and gas content of epigenetic mineralization in the salt column of the Verkhnekamskoe deposit (on the example of the Usolsky mine)

Research subject. The paper considers the tectonic position of zone epigenetic mineralization in salt strata one mines Verkhnekamskoye deposit, gross and microelement chemical composition, gas content component composition gases. Materials methods. To assess original formations, structural geological observations were carried out mine workings, sampling, determination (XRF, Bruker S8 Tiger spectrometer), trace elements (Aurora M90 inductively coupled plasma mass associated gases (gas chromatograph 450-GC company “Varian, Inc”). Results. It has been established that vein fills delamination cracks cores synclinal fold is accompanied by zones halite leaching sylvite recrystallization. Further down section, possible sources K-oversaturated brines are recorded, which generated numerous small structures such as pop-ups or kink bands. enrichment light hydrocarbon gases, well easily soluble salts mobile (KCl, CaCl 2 , MgCl Br, Rb, Li, Sr, Zn, Cu, Co, Te, Se, Sn, Pb), reflects their formation from sediment-brines mobilized during folding sylvinite rocks. Conclusions. One mechanisms for mobilization fluids, salts, column characterized, with folded appearance scattered chambers lower silyvinite bed KrIII subsequent pulsating migration up section along bends larger folds KrII. shown process mineralization, differentiation occurs, different sorption properties halite, sylvin, clay material.
