Abstract
Detrital zircon U-Pb chronology database of Precambrian deposits provides a context for the interpretation of the origin and evolution of the ancient crust. Here, we tried to summarize the published literature containing detrital zircon U-Pb ages and Hf isotope data of Precambrian deposits in South China, and then established a database, which contains details of information, such as reference, sample ID, locality, rock type, research institution, GPS coordinates, U-Pb ages, εHf(t) values, etc. The data statistics of this paper rely on the OneSediment Working Group of The Deep-time Digital Earth program (DDE). By November 2022, 610 samples with 38278 U-Pb ages and 8798 Lu-Hf isotope data were collected from 136 papers, and these data can be downloaded from DDE Data Publish & Repository website, https://repository.deep-time.org/. The purpose of the establishment of the dataset is to provide guidance and convenience for the research direction of future generations in South China, and to improve the previous studies through the integrated data to avoid the waste of resources caused by a large number of repeated studies.
