Measured isotope activity ratios, calculated ages and monte-carlo derived age...
A total of 32 230Th ages were measured along the growth axis of SIB-4 stalagmite. 100-200 mg of calcite powder was drilled per sample in a laminar-flow hood following growth... -
Measured SC02 U/Th isotope activity ratios, calculated ages and monte-carlo d...
U-Th ages were calculated using the initial detrital 230Th/232Th value of 111 ± 41 ppm, which was previously calculated for SC02 based on two isochrons measured in separate...
