dc.description.abstract	The paper presents results of Ar and He isotopic studies in rocks and sulfide ores of the Late Precambrian Dovyren dunite-troctolite layered intrusion (Northern Baikal region). The 3He/4He and 40Ar/36Ar ratios in the intrusion are similar to those in other mafic intrusions in the continental crust, and the gases in fluid inclusions bear a significant crustal component. The lowest 3He/4He and 40Ar/36Ar ratios in sulfide ores hosted by the intrusion, about those in crustal fluids, indicate involvement of the latter in magmatic mineralization.
