Resolving the tectonic setting of South China in the late Paleozoic

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.
