TY - DATA T1 - The geochemical and zircon U-Pb dating data of the Milai section in the Gonjo Basin, Southeast Tibet PY - 2023/12/18 AU - Ruiyao Zhang AU - Chunju Huang AU - David B.

The geochemical data (in our case Rb/Sr and Ti/Ca data) were measured using an Innov-X Systems X-ray fluorescence (XRF) spectrometer, and used to carried out cyclostratigraphic analysis (and establish a floating astronomical timescale) and trace orbital-scale climate changes in the Gonjo Basin. The zircon U-Pb dating were performed using an Agilent 7900 ICP-MS equipped with a coherent 193 nm excimer laser ablation system (GeoLas HD) and identified the age of the volcanic layer at 866 m in the Gonjo Basin, and anchored in numerical time in order to obtain an absolute astronomical timescale.
