| Abstract: | U-Pb SHRIMP-dating of zircons from twenty five intrusions representative of the Main granitoid batholith belt and associated
dike swarms (Yano-Kolyma gold bearing province, North East of Asia) are mostly ∼150 ± 3 Ma (Kimmeridgian-Tithonian). Two less
widespread impulses of magmatism dated at 160–155 Ma and 146–143 Ma representing the full range of ages present in the Main
belt. Paleoproterozoic (∼1.8 Ga) inherited zircons were found in three intrusions from the south-western part of the belt
where Precambrian crust of the North-Asia craton is inferred to underlie it.
