ZARECHENSK BARITE-POLYMETALLIC DEPOSIT AND SOME CONDITIONS OF ITS ORE ACCUMULATION
Abstract
Zarechensk barite-polymetallic deposit is located in the northwest part of Ore Altai megatrough, which has long-lasting history of its development and complicated geological structure. Within the ore district, which is the northwest part of the devonian Zmeinogorsk-Bystrushinsky trough, ore mineralization is associated with the system of northwest border faults and cross branch faults. At these deposit four main stages and five phases of minerogenesis were determined. The first stage is the stage of oregenesis beginning and quartz-chlorite-sericite wall-rock alteration rocks formation. Ore deposition and intense tectonics took place during the second stage. The third stage is the most longstanding and productive ore formation stage. There are five distinct minerogenesis phases within this stage. The fourth stage expressed in erosion development and supergene alteration of already formed ore bodies with oxidation zone formation. Main ore minerals are pyrite, chalcopyrite, sphalerite and galena. Minor minerals are tetrahedrite, bornite, tennantite and chalcocite. Precious metals minerals are acanthite, gold, electrum, gold and silver amalgams. Barren minerals are barite, quartz, calcite, gypsum. According to obtained data average isotopic composition of second stage sulphides is: pyrite -0,9?, chalcopyrite -1.5?, galena +0,5?, sphalerite -1,9? for the first complex; chalcopyrite -4,6?, galena -3,0?, sphalerite +3,9?, tetrahedrite -3,7? for the second complex; tennantite -12,8?, bornite -8,9? for the third complex. Sulfur isotopic compoisiton variations indicate source inhomogeneity. Thus, there was dominant source change from mantle one in the beginning to crustal one in the end. Main oregenesis stages took place in the range of temperatures between 190 and 210В°? and in the mineral-forming solutions salinity range between 5.5 and 11 wt % NaCl equiv.
