Abstract

The tectonic setting of South China during the late Paleozoic is essential to understanding the geodynamics off the eastern margin of Pangea supercontinent due to its unique paleo-position at the confluence of the Paleo-Tethys and Panthalassic oceans. Here, we present integrated biostratigraphic, geochronological, and isotope geochemical data on the late Carboniferous siliciclastic rocks from southeast South China in order to decipher the tectonic evolution of the South China Block.  We collected three siliciclastic samples from the section at stratigraphic heights of 0.6 m, 16 m, and 26 m. The U-Pb age dating of detrital zircons was conducted by LA-ICP-MS at the Tianjin Center of Geological Survey. Glass NIST 610 was used as external standards for trace element calibration. Zircon Hf isotopic data were conducted by LA-MC-ICP-MS at Nanjing FocuMS Technology Co. Ltd. We also compiled zircon U-Pb age data and Hf isotopic data  from previously published sources, including Hu et al. 2015, Hu et al. 2012, Li et al. 2020, 2017 and Li et al. 2012.
