calibration, since this calibration is derived solely from cave carbonates precipitated at Earth surface temperatures Both isochrons show a decreasing trend in T Δ47 towards the centre of the drip cup, with maximum reconstructed temperatures of 32.6°C ± 3.4°C and 33.0°C ± 3.2°C measured in the left and right subaerial zones, respectively, and minimum temperatures of 26.0°C ± 3.2°C and 22.1°C ± 2.5°C found in the left/right subaqueous zones.
