Abstract - Summary 
(short description):
Fluid inclusions study of vein quartz from “Lis’y Gory” (“Fox Mountains”) multilevel hydrothermal system have made. This hydrothermal system is located on the southern flank of the East-Magnitogorsk paleoisland arc. Gold-bearing zones (the East, the Central, the West zones) are confined to definite stratigrafical levels of host stratum. Our quartz samples are from the rock heaps of the West and the East zones and from hematite-quartz edifices. New data showed that hydrothermal mineralization of different stratigrafical levels of “Lis’y Gory” system has similar parameters of fluids. It means seawater is the same hydrothermal sourse for hematite-quartz edifices and gold-bearing zones of sulfidized andesibasalts. Our measures of fluid inclusions from quartz of gold-bearing zones from “Lis’y Gory” field showed that fluids have NaCl-composition with salinity of 0.5–9.2 wt %. Their temperatures are 230–270 °Ñ. There is the wide interval of fluid salinity because of possible magmatic component of solutions.
