摘要
Zircons collected from volcanic tuff rock samples from the upper part of the Chuanlinggou Formation in Kuancheng County, Hebei Province, were dated using the SHRIMPII at Beijing SHRIMP Center. The zircon U-Pb age obtained is 1621±12 Ma (MSWD=0.56) of 206Pb/238U age. Combined with numerous SHRIMP zircon U-Pb ages in other publications, chronological column of this area was determined. This provides new evidence for the Geological Time Scale of the Changcheng System (Ch, 1.8~1.6 Ga), which has been reconfirmed by the Commission of Stratigraphy of China.
