A detrital zircon dataset for the eastern Central China Orogenic Belt (East Qinling, Dabie and Sulu orogens)

The Qinling-Dabie-Sulu orogen is the eastern part of the Central China Orogenic Belt. Looking back on previous studies of the sedimentary record we systematically compiled the dataset of detrital zircon U-Pb ages and Hf isotopes for this orogenic belt. The dataset incorporates a comprehensive compilation of 32,449 detrital zircon U-Pb ages and 979 Hf isotopes. The findings demonstrate that distinct tectonic units within the orogenic belt exhibit unique tectonic evolution histories during various geological epochs. This dataset can be used to constrain the tectonic framework and orogenic evolution including ocean subduction, continental collision and orogen exhumation. It can be integrated with other geological datasets to improve our understanding of the Central Orogenic Belt in China, and possibly plate tectonics globally.

Automated summary

This study systematically investigates the Qinling-Dabie-Sulu orogen in the Central China Orogenic Belt and compiles a large dataset of detrital zircon U-Pb ages and Hf isotopes. The findings reveal unique tectonic evolution histories for different tectonic units within the orogenic belt during various geological epochs. These data can help constrain the tectonic framework and orogenic evolution, contributing to a better understanding of the Central Orogenic Belt in China and global plate tectonics.
