The Taining Geopark in Fujian is characterized by young Danxia landform consisting of red beds of the Cretaceous Shaxian Formation and Chongan Formation. A thick volcanic interbed occurs in the lower Chongan Formation in the Fengdong area near the Jinhu Lake. This is the only volcanic interbed in the Chongan Formation in Fujian Province and provides an opportunity to determine the accurate age of the Danxia red beds. The volcanic interbed was formed in two episodes of rhyolitic eruptions, and gives a zircon LA ICP-MS U-Pb age of 98.52±0.96 Ma. Thus, the Danxia red beds of the Taining Geopark were deposited at the transition between the Early and Late Cretaceous, rather than in the middle-late stage of the Late Cretaceous as proposed previously. The age and geological setting of Danxia red beds in South China need to be reconsidered. The new data from Fujian Province are also valuable in the study of other Chinese geoparks of Danxia landform.
