Supplementary data and code for Early Miocene Yangtze sediment delivery recorded in the East China Sea terminal sink

Abstract

This record contains the supplementary data and Python source code associated with the manuscript “Early Miocene Yangtze sediment delivery recorded in the East China Sea terminal sink” by Yao et al. The dataset supports analyses of detrital-zircon U–Pb crystallization ages, trace-element compositions, zircon fission-track (ZFT) cooling ages, and paired U–Pb–ZFT age distributions from Cenozoic sandstones in the East China Sea Shelf Basin. It also includes modern-river reference data and compiled regional paired-age records used for provenance comparisons. Files included Supplementary Data.xlsx: A combined workbook containing Supplementary Data 1–7, including sample and stratigraphic metadata, zircon analytical results, modern-river reference ages, provenance statistics, paired-age analyses, and published regional reference data. Supplementary Software.zip: Python source code, the master input workbook, dependency specifications, a README, and an MIT License file. The package reproduces the Python-generated main figures (Figs. 2–4), Supplementary Figs. 1, 2, 4, 5, and 7–9, derived Supplementary Data 5–6, and associated validation outputs. Reproducibility Extract Supplementary Software.zip, install the Python dependencies listed in requirements.txt, and run: python run_all.py The software was tested using Python 3.13.5. Licensing and data provenance The Python source code is released under the MIT License. The separately archived data workbook is not covered by the MIT software license. Previously published third-party data retain their original attribution and reuse conditions, and the corresponding source publications are cited in the manuscript and supplementary materials.
