a Strontium to calcium ratios (Sr/Ca, circles) and stable carbon isotopes (δ13C, solid line) measured in flowstone BA7-1 from Bàsura cave (northern Italy, this study). b Cross plot (r = 0.88, p < 0.001) of δ13C and Sr/Ca data in BA7-1 (this study). c BA7-1 growth rate (this study). d Speleothem δ18O from Sanbao cave in eastern China48. e BA7-1 stable oxygen isotopes (δ18O, this study). The 429–457 kyr BP hiatus is indicated by the grey shading. Marine Isotope Stages (MIS) 11c and 12 defined in ref. 1 are given at the top. Color-coded error bars in (a) and (d) are the U-Th ages with 2σ errors from Bàsura and Sanbao caves, respectively.
