for the Fish Canyon sanidine standard, and improved accuracy for 40 Ar/ 39 Ar geochronology
Ar/ 39 Ar and K-Ar geochronology have long suffered from large systematic errors arising from imprecise K and Ar iso- topic data for standards and imprecisely determined decay constants for theExpand

Statistical Methods for Jointly Estimating the Decay Constant of 40K and the Age of a Dating Standard
To simultaneously evaluate the decay constant of 40K (λ) and the age of a standard (tstd) using isotopic data from geologic materials, we applied a series of statistical methods. The problem ofExpand

Late Mesozoic and Cenozoic thermotectonic evolution along a transect from the north China craton through the Qinling orogen into the Yangtze craton, central China
[1] Cretaceous and Cenozoic reactivation of the Triassic Qinling-Dabie orogen between the north China and Yangtze cratons resulted from the combined effects of Pacific subduction–back-arc extensionExpand

Low-Temperature Thermochronometry of Meteorites
Timing of accretion of the primary planetesimals in the early solar system has been investigated using short-lived (e.g., 26Al, 53Mn, 182Hf and 129I) and long-lived (e.g., 238U, 235U, 232Th andExpand
