Fig. 3

a Precipitation temperatures obtained from clumped-isotope analyses are depicted along with uncertainties reported as ±2σ. Oblique lines are the calculated oxygen isotopic values of the mineralizing fluids δ18Owater (see “Methods” section). b Photographs show a selection of analyzed hand samples. Numbers in parentheses are U-Pb ages and T47. The composition of seawater and meteoric water composition in Tortonian and Messinian are from refs. 87,88,89,90.
