Uranium-Thorium dating of authigenic carbonates and shells from Yam Seep, South China Sea

This data presents high precision Th/U ages from seep carbonates obtained from a 5-meter-long rock core (GeoB 23225-1, MeBo24) collected by the sea floor drill rig MARUM-MeBo200 in Yam Seep, SW offshore Taiwan during SO266, RV Sonne. The dating results provide records of over 40 thousand years old gas seepage and an unconventional precipitation sequence throughout the 5-meter downcore. The oldest age presents at ~192 cmbsf and the youngest age at the lower end of the core (~490 cmbsf). It provides insights into gas seepage episodes at active margin as well as precipitation sequences influenced by fracturing. Uranium and thorium isotope measurements were performed at the Institute of Environmental Physics multi-collector ICPMS facility in Heidelberg, which hosts a ThermoFisher Neptuneplus MC-ICPMS following the method of Wefing et al., (2017) and Frank and Hemsing (2021). Coordinate GeoB 23225-1 (Lat. Lon.): 22° 03.487' 119° 47.979'; Water depth: 1352 mbsl.
