ObjectivernCretaceous terrestrial red beds, as a major component of the Danxia Landform, are widespread in South China. However, the lack of fossils with absolute ages as well as scarce volcanic rocks for isotopic dating to constraint the boundary ages of the red beds results in unclear formation ages of the Danxia red beds. Recently, we have conducted a study of LA-ICP-MS zircon U-Pb dating on the tuffs present at the basal part of the Cretaceous red beds in the Taining Basin, Fujian Province, and obtained high precision age. The new age not only can precisely constrain the formation age of the Danxia red beds in the Taining Basin, but also provide important evidence for the study of regional stratigraphic correlation, paleoclimate, basin evolution and tectonic setting.
