Evaluating uncertainties in the calibration of isotopic reference materials and multi-element isotopic tracers (EARTHTIME Tracer Calibration Part II) (2015, methodology): “…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 of assumed coeval geological materials (e.g. Renne et al., 2010; Nebel et al., 2011) and the accurate calibration of geologic time through U–Pb geochronology.”
Time scale controversy: Accurate orbital calibration of the early Paleogene (2012, methodology): “[2] Temporal relations are the key to causality arguments in Earth’s history [Renne et al., 1998; Min et al., 2000; Kuiper et al., 2008; Renne et al., 2010].”
U–Th–Pb zircon geochronology by ID-TIMS, SIMS, and laser ablation ICP-MS: Recipes, interpretations, and opportunities (2015, background): “It is also critical to avoid mistaking inter-187 chronometer bias such as between U-Pb and 40 Ar/ 39 Ar chronometers (e.g., Renne et al., 2010) 188 for a real age difference.”
Best Practices for Justifying Fossil Calibrations (2011, methodology): “40Ar/39Ar and U-Pb ages differ systematically by ∼1%, something that requires correction prior to comparison (e.g., Renne et al. 2010).”
