Data Publisher & Repository

With the development of detrital zircon U–Pb ages and Hf isotope analysis as conventional sedimentological research methods, a large number of studies have been conducted in the Tarim, West Kunlun, Tajik, Pamir, and Tianshuihai regions and abundant data have been accumulated. Summarizing these data to characterize sedimentary units and source regions is more important than local studies of specific geological epochs; therefore, we compiled a database of detrital zircon U–Pb ages and Hf isotope analyses from the Tarim, West Kunlun, Pamir, Tajik, and Tianshuihai terranes. The database contains data from 90 papers, including 35,232 individual U–Pb ages and 4181 Hf isotope analyses. The database records the literature source, petrologic sample information, regional geological information, geographic coordinates, and analytical parameters for each data point in as much detail as possible to allow readers to review, process, analyse, and use the data. The database relies on the Deep-time Digital Earth (DDE) platform and uses an open database update system to enable sharing and collaborative building. We encourage other researchers to contribute relevant published data to facilitate wider use.
