Abstract

Abstract

The Naij Tal Group is a major lithostratigraphic unit with a complex composition in the East Kunlu Paleozoic orogenic belt, and there has long been debate on its formation time. The An average SHRIMP zircon ²⁰⁶Pb/²³⁸U age of 450.4 ± 4.3 Ma has been obtained for 15 rhyolite samples collected from the Shihuichang Formation of the Naij Tal Group south of Gelmud. It was interpreted as the age of a volcanic activity, so the Shihuichang Formation of the Naij Tal Group can be considered to form in the Late Ordovician.
- Naij Tal Group,
- zircon U-Pb age,
- Late Ordovician,
- eastern Kunlun orogenic belt
