Age of granitoid plutons, North Chukotka: Problem formulation and new SHRIMP U-Pb zircon datings

A brief review of present day ideas about the age of granitoid plutons in the Chauna zone of the VerkhoyanskChukotka fold belt and results of SHRIMP U-Pb zircon dating in two large plutons, Velitkenai and Moltykan, are presented. In spite of structural differences, both plutons are characterized by...

Zusammenfassung:A brief review of present day ideas about the age of granitoid plutons in the Chauna zone of the VerkhoyanskChukotka fold belt and results of SHRIMP U-Pb zircon dating in two large plutons, Velitkenai and Moltykan, are presented. In spite of structural differences, both plutons are characterized by a similar isotopic age.
