Chronology reconstruction from radionuclide activities of 137Cs, 210Pb and 226Ra for (A) the Huguangyan Maar Lake (HGY) and (B) the Chaohu Lake (CH). (A1 and B1) unsupported 210Pb versus cumulative dry mass; (A2 and B2) chronology reconstructed from the constant rate of supply (CRS) model (upper black line; horizontal lines indicating uncertainties) and the calculated mass accumulation rates (MARs, purple line); (A3 and B3) 137Cs profiles are in good agreement with the starting of global nuclear testing of ~1952-53 and the global nuclear fallout of ~1963-64 reconstructed by the CRS model.
