Abstract - Summary 
(short description):
The evolution of hydrothermal fluids was estimated by compositions of chlorites and ore minerals, fluid inclusions data and gas chromatography results. The main trend of temperature evolution is a steep decrease, but each stage started at higher temperature environment than the previous one. General model of ore deposition is as follows 1) mixing of fluids of two types: first –reduced (Fe- and S-rich) and, probably, ore-bearing, and second – oxidized (Mg-rich) vadose water; 2) cooling of a hotwater (nonboiling) geothermal fluid.
