Abstract
40Ar/39Ar dating (23 determinations) has been carried out for magmatic and ore-metasomatic processes in the Sora copper-molybdenum ore region. Formation of the large Sora porphyry Cu-Mo deposit related to the evolution of an ore-bearing porphyry complex was preceded by long formation of multipulse granitoid magmatism, separate pulses of which were accompanied by the occurrence of Cu
