摘要: A comprehensive treatment of the derivation U-Pb isotope ratios and their corresponding uncertainties from dilution thermal ionization mass spectrometric measurements is presented. Standard parametric statistical methods error propagation are utilized to convolve associated with instrumental fractionation, tracer subtraction, blank Pb U initial common correction. Derivations include errors correlations for total sample U/Pb (including radiogenic Pb) two- three-dimensional isochron calculations, concordia model age ratios.
