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...

DISTANCE [cm] is the distance from rim. For each specimen the first value represents the age of the outermost layer of the skeleton, taken as equal to the sampling year. Sample...

The 14C reservoir age of the surface ocean was determined for two Holocene periods (4908-4955 and 3008-3066 calendar (cal) B.P.) using U/Th-dated corals from Biscayne National...

Sediment depth is given in mcd. Raw age is calculated directly from the data in the previous two columns. Scavenging corrected age = the age corrected for initial 230Th by...

(Table 1) Th and U isotope ratios of sediments from ODP Site 166-1009

U and Th blanks are <1‰ of the measured sample and are corrected for. Raw ages and delta234U values are adjusted to account for initial 230Th to give the corrected numbers in...
