Comment:
U decay constants: l238 = 1.55125x10-10 (Jaffey et al., 1971) and l234 = 2.82206x10-6 (Cheng et al., 2013). Th decay constant: l230 = 9.1705x10-6 (Cheng et al., 2013).
o account for uplift, 0.3°C was subtracted to all temperatures.
M6-1-20 is a 22 cm tall stalagmite from Neotektonik Cave which grew from about 6.6 ka BP to presen day (Arps, 2017).
