ter12077-sup-0007-TableA3.pdfapplication/PDF49KTable S3. U-Pb data for WP045 zircons analysed by CA-TIMS (Figs 5 and A2).

ter12077-sup-0001-FigureA1.pdfapplication/PDF313KFigure S1. δ13C vs. δ18O cross-plot of carbonates from the Muraykhah Formation, revealing no distinct correlation and a wide spread in both δ13C and δ18O values, with notably 18O-enriched values occurring in all three sections.
ter12077-sup-0002-FigureA2.pdfapplication/PDF1760KFigure S2. A. CL image of select zircons from sample WP045. Notice the bright cores and dark rims, which yield distinct trace element signatures (B–D). B-D. LA-ICP-MS measurements of cores and rims of zircons. Data plotting between the fields of the cores and rims are interpreted to reflect mixed spots. E. Age spectra for the WP045 zircons analysed by LA-ICP-MS. The youngest zircons, shown in green, yield a weighted mean age of 619.1 ± 4.6 Ma (n = 10), which is identical within error to the CA-TIMS age presented in Figure 6.
