In the original publication # we applied a 238U/232Th detrital ratio of 0.197 by weight. # # Variables: # depth Depth (cm) # Th232 Thorium-232 # U238 Uranium-238 # # CORE: VM22-177 depth Th232 Th232_err U238 U238_err 5 7.15E-07 1.04E-08 1.86E-07 1.97E-09 15 7.96E-07 9.3E-09 1.89E-07 2.38E-09 25 8.84E-07 7.34E-09 2.31E-07 3.03E-09 35 8.23E-07 1.18E-08 2.69E-07 2.63E-09 35 8.53E-07 1.17E-08 2.71E-07 2.42E-09 45 1.21E-06 9.12E-09 2.63E-07 3.94E-09 55 1.14E-06 1.08E-08 1.91E-07 1.39E-09 65 1.23E-06 1.42E-08 2.86E-07 5.18E-09 75 1.12E-06 1.04E-08 2.04E-07 2.76E-09 85 9.74E-07 1.78E-08 1.87E-07 3.9E-09 95 1.05E-06 1.46E-08 2.14E-07 2.48E-09 105 1.35E-06 2.76E-08 2.61E-07 2.78E-09 115 1.64E-06 2.19E-08 4.04E-07 1.91E-09 125 3.04E-06 3.14E-08 7.96E-07 6.21E-09
