A new early dinosaur (Saurischia: Sauropodomorpha) from the Late Triassic of Argentina: a reassessment of dinosaur origin and phylogeny (2010, background): “However, there is a discrepancy between U-Pb and 40Ar/39Ar dates, the latter being 0.5–1% younger (Schoene et al. 2006).”
Time scale controversy: Accurate orbital calibration of the early Paleogene (2012, result): “This is 300 kyr older than the astronomically calibrated age and supports the findings that U/Pb dates are systematically older than 40Ar/39Ar dates [Min et al., 2000; Schoene and Bowring, 2006; Schoene et al., 2006].”
U–Pb systematics of the McClure Mountain syenite: thermochronological constraints on the age of the 40Ar/39Ar standard MMhb (2006, methodology): “1971), but many authors note that the value of the (238)U decay constant is likely the more accurate of the two based on evaluation of the quality of the experiments (Begemann et al. 2001; Mattinson 1994, 2000; Schoene et al. 2006; Schön et al. 2004).”
Astronomical calibration of the Paleocene time (2008, background): “Unfortunately, because of the relatively large errors in radiometric dating it is still impossible to verify if U–Pb dates are systematically b1% older than 40Ar/39Ar (Schoene and Bowring, 2006; Schoene et al., 2006).”
An algorithm for U‐Pb isotope dilution data reduction and uncertainty propagation (2011, methodology): “…tracer and decay constants also contains elements for any covariance between the two, whichwould be incurred if for instance the 235U decay constant were recalibated to the 238U decay constant using closed system zircon analyses spiked with the same tracer [Schoene et al., 2006;Mattinson, 2010].”
for the Fish Canyon sanidine standard, and improved accuracy for 40 Ar/ 39 Ar geochronology (2010, methodology): “U/Pb zircon data from this sample were reported by Schoene et al. (2006).”
U–Th–Pb zircon geochronology by ID-TIMS, SIMS, and laser ablation ICP-MS: Recipes, interpretations, and opportunities (2015, background): “, 2012) and of uranium decay constants (Schoene et al., 2006; Mattinson, 2010; Boehnke and Harrison, 2014).”
Community‐Derived Standards for LA‐ICP‐MS U‐(Th‐)Pb Geochronology – Uncertainty Propagation, Age Interpretation and Data Reporting (2016, background): “This is similar to practice in the ID-TIMS UPb community where quotation of three levels of uncertainty is recommended (Schoene et al. 2006).”
GRENVILLE SKARN TITANITE: POTENTIAL REFERENCE MATERIAL FOR SIMS U–Th–Pb ANALYSIS (2010, background): “The calculated ages and concordia diagrams rely on the 238U decay constant of Jaffey et al. (1971), 1.55125 3 10–10, and the revised 235U decay constant of Schoene et al. (2006), 9.8569 3 10–10.”
Evaluating uncertainties in the calibration of isotopic reference materials and multi-element isotopic tracers (EARTHTIME Tracer Calibration Part II) (2015, methodology): “…with the 235 U and 238 U decay constant data (Jaﬀey et al., 1971) legitimizes further eﬀorts at inter-calibrating the U decay constants (e.g. Schoene et al., 2006; Mattinson, 2010; Cheng et al., 2013) as well as the U–Pb system with other radio-isotopic dating systems through the analyses…”
The origin and early radiation of dinosaurs (2010, methodology): “…(Triassic–Jurassic boundary) is well constrained to between 202 and 201 Ma by U–Pb ages and magnetostratigraphic data (e.g., Kent and Olsen, 1999; Schoene et al., 2006; Schaltegger et al., 2008; Jourdan et al., 2009), with an estimated age of 201.3 Ma based on cyclostratigraphy (Whiteside et…”
