40AR/39AR age of the Albyn gold ore deposit (eastern part of the Mongol-Okhotsk fold belt)

It was established that the age of hydrothermal metasomatites of the Albyn gold deposit, one of the most famous in eastern Asia, can be estimated at 135-131 Ma. It is assumed that the formation of this deposit is associated with dislocations and metamorphism of volcanogenic-sedimentary strata of the Mongol-Okhotsk belt.
