摘要：

The junction of Caledonides and Hercynides structures in West Siberia and Eastern Kazakhstan, which were defined as a single Ob-Zaisan fold zone, host abundant and various types of ore systems. For age determination Ar/Ar (sericite) and U-Pb (SHRIMP) methods were used. Three basic age boundaries of formation of ore mineralization are established: Late Carboniferous, Early Permian and Early Triassic. Our data suggest the similarity of metallogeny of the two gold-ore regions and a single trend of evolution of magmatism and ore formation. As to the age aspects, these regions in magmatism and metallogeny correlate with similar structures of NW China and Central Asia. The age of all large Au-As deposits in this region fits within a narrow time interval: 285 +/- 3 Ma
