| Summary : Rigorous Data Reduction and Error Propagation of Ar40 / Ar39 Data
|
Description :
Processes noble gas mass spectrometer data to determine the isotopic
composition of argon (comprised of Ar36, Ar37, Ar38, Ar39 and Ar40)
released from neutron-irradiated potassium-bearing minerals. Then uses
these compositions to calculate precise and accurate geochronological
ages for multiple samples as well as the covariances between them.
Error propagation is done in matrix form, which jointly treats all
samples and all isotopes simultaneously at every step of the data
reduction process. Includes methods for regression of the time-resolved
mass spectrometer signals to t=0 (\'time zero\') for both single- and
multi-collector instruments, blank correction, mass fractionation
correction, detector intercalibration, decay corrections, interference
corrections, interpolation of the irradiation parameter between neutron
fluence monitors, and (weighted mean) age calculation. All operations
are performed on the logs of the ratios between the different argon
isotopes so as to properly treat them as \'compositional data\', sensu
Aitchison [1986, The Statistics of Compositional Data, Chapman and
Hall].
