Muruntau Mineral Gold Ore Photo Imagn

We reinterpret the regional geologic setting of the giant Muruntau gold deposit and report new 40 Ar 39 Ar isotope age determinations and a laser Raman microprobe analysis of fluid inclusions. New 40 Ar 39 Ar isotope age determinations of hydrothermal sericite selvages to gold-stage quartz veins are in excellent agreement with older Rb-Sr dates on auriferous quartz veins.
