U-Pb SHRIMP ages of granitoides from the main batholith belt (North East Asia)

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.
