Stable isotope data showing typical carbonate sedimentary cycles in lacustrine carbonates from the Upper Freshwater Molasse between 45.0 and 41.0 m. Cycle boundaries shown by red dotted lines, with δ13C trends shown by red arrows: sharp cycle bases at flooding events with onset of open lacustrine conditions; gradual depletion in δ13C towards the top of sedimentary cycles associated with increased concentration of 13C-depleted organic matter
